The ESP32 3.2 Inch TFT Touch w/ Camera is the 3.2-inch version of the ESP32 touchscreen display, based on ESP32-WROVER, with a built-in 2M pixel OV2640 camera. The LCD is 320x240 TFT, with driver is ILI9341, it uses SPI for communication with ESP32, the SPI main clock could be up to 60M~80M, make the display smooth enough for videos and the camera OV2640 with pixel 2M, with this camera, you can make applications such as remote photography, face recognition.

While the camera is not used, you can freely use all these pins with the breakout connectors, to connect the ESP32 display with sensors/ actuators, suitable for IoT applications. This 3.2-inch ESP32 display is fully compatible with the Adafruit Arduino ILI9341 libraries, which make it easy to use with Arduino.

This ESP32-CAM Project covers how to use ESP32-CAM with a TFT display to show the picture captured by the cam. We have covered several times how to use ESP32-CAM in different projects and we have described how to use ESP32-CAM in Machine Learning projects. Even if we can use ESP32-CAM with a Web server to show pictures, in this post we want to cover how to show a picture on a TFT screen (ST7735). Therefore, we would like to visualize the picture taken by the ESP32-CAM directly on the display. In this case, we use an ST7735s display, anyway, you can select a different TFT if you like.

You should already know how to take a picture using an ESP32-CAM therefore we will focus on two aspects only:How to connect the ESP32-CAM to TFT display

This is the most interesting part because here we will show the picture taken by the ESP32-CAM on the TFT display. To do it, we will use the TJpg_Decoder library because it simplifies our work. First of all, we use a low-resolution such as 120×160 so that the picture fits in the TFT.

defining the scale and the callback method used to render the picture:bool tft_output(int16_t x, int16_t y, uint16_t w, uint16_t h, uint16_t* bitmap){

At the end of this tutorial, you have learned how to use ESP32-CAM with TFT display. In this project we have integrated ESP32-CAM with ST7735 to show the image captured. We have build a simple camera machine using ESP32-CAM.

ESP32 development boards with a camera are becoming very popular among the maker community. There are several models with different features like microSD card support, microphone, screen, and much more for a very reasonable price. These boards allow you to build projects with image, video streaming, face recognition and detection, and other AI applications. Do you know what’s the best ESP32 camera board for your project?

All cameras have an OV2640 camera and usually, these come with a small flex cable. There are camera probes sold separately with longer flex cables and with a fish-eye lens. The fish-eye lens capture a wider area, which is really useful for surveillance projects.

The ESP32-CAM AI-Thinker is one of the most popular ESP32 development boards with a camera – it comes with a lot of useful features and costs around $7 or less!

It features an ESP32-S chip and comes with a “regular” 2MP OV2640 camera. This board has 4MB PSRAM, which is used for buffering images from the camera into video streaming or other tasks and allows you to use higher quality in your pictures without crashing the ESP32.

It supports a microSD cardand has 10 accessible GPIOs and power pins. However, not all GPIOs can be used because some are either being used by the camera or by the microSD card. So, you need to be careful with which GPIOs you’ll use.

The ESP32-CAM board comes with an on-board antenna, but also with an IPEX connector allowing you to alternatively use an external antenna to improve the Wi-Fi communication range.

One of the major drawbacks of the ESP32-CAM is that it doesn’t have USB-to-UART interface. This means that you can’t connect the ESP32-CAM directly to your computer using a USB cable. You need to use an FTDI programmer. Nonetheless, this is one of the most versatile and cheapest ESP32 development boards with a camera.

This development board comes with the ESP32-Wrover-E chip (with PSRAM). It comes with the OV2640 camera and it is easy to use and set up. It has a USB-to-UART converter so it’s straightforward to upload code to the board. You just need to connect a USB cable to the board and connect it to your computer to upload code or apply power. There’s no need for extra circuitry or an FTDI programmer.

It comes with several exposed GPIOs if you want to connect other peripherals. Additionally, if you’re not using the camera, you can use it as a regular ESP32 with a wide number of available GPIOs. It comes with RESET and BOOT buttons, which makes it easy to reset the board or put it in flashing mode if needed.

When programming this board using Arduino IDE, make sure you select the board ESP32 Wrover Module and in the partition scheme select Huge APP (3MB No OTA/1MB SPIFFS).

Just with 21mm by 41mm, it is equipped with a 2 MP OV2640 camera, on-board microphone, reset, boot, and function buttons, and two LEDs. It features 4MB Flash, 8MB PSRAM, and a Micro USB type-C connector (easy to upload code). It comes with on-board antenna and IPEX connector if you want to add an external antenna.

There are several different versions of M5-Stack ESP32 boards with cameras. The M5-Camera A or M5-Camera B like all the other boards featured here comes with the OV2640 camera. It has 4MB PSRAM—so, you shouldn’t have problems taking pictures and streaming with higher quality.

The TTGO T-Camera Plus comes with all the functionalities we would want in such a development board and for a very reasonable price. The board comes with microSD card support, a microphone, support for a 3.7V lithium battery as well as a battery management circuit, a 1.3 TFT display (color screen), microUSB interface, and on-board reset button.

Finally, the board has an on-board antenna, but also an IPEX connector if you want to add an external antenna. When we got our board it came loaded with an example that shows what the camera “sees” on the screen. This is a very versatile board and we really like it. Read our in-depth review of the TTGO T-Camera Plus.

This camera features a OV2640 camera, a 0.96 inch SSD1306 OLED display, a grove connector (ideal to connect I2C devices), a battery connector, a PIR motion sensor, an on-board RESET button, and a function button connected to GPIO 34. It also features 8MB PSRAM, but it doesn’t support a microSD card.

If you want to include some motion detection in your projects, this is the camera to go with. For more details, you can take a look at the camera GitHub page.

The TTGO T-Journal is a $12-$15 ESP32 Camera Development Board with an OV2640 camera, an external antenna, an I2C SSD1306 0.91 inch OLED display, some exposed GPIOs, function button, a battery connector, and a micro-USB interface.

The OLED display is a great addition to the board. You can display the board IP address, or any errors while debugging. There are four accessible GPIOs. Two of them are for I2C communication and the other two are perfect to connect servo motors (you can also connect other peripherals).

This is another ESP32 board with a camera from M5-Stack. This ESP32-Camera doesn’t have PSRAM. In practical terms, this means the camera is not able to do face recognition and detection and doesn’t support picture resolution higher than SVGA (800×600). You may also have a hard time with video streaming. Some people reported that his camera heats up very fast with video streaming. Usually, when you get one of these boards, you also get a heat sink precisely because of that.

In this article, we’ve reviewed 8 different ESP32 camera development boards. All boards feature the OV2640 2MP camera and you can program them using Arduino IDE. The best camera for you will really depend on your project requirements. We compiled all this information so that it’s easier for you to pick up the best board for what you have in mind.

In our opinion, the ESP32-CAM AI-Thinker is the most versatile for beginners (and it’s also cheaper) but it needs an FTDI programmer to upload code, or an ESP32-CAM MB programmer. If you don’t want to use the FTDI programmer there are other boards to choose from, I personally like the Freenove ESP32 Wrover board.

The TTGO T-Plus is the one with more functionalities: microphone, microSD card, a color screen, and much more. If you don’t intend to connect any peripherals to your board, the M5-camera might be a better option (and you can easily connect other M5-stack expansions). At this point, taking into account the variety of available boards, I would not choose a board without PSRAM.

Register in our brand new ESP32 course with Arduino IDE. This is our complete guide to program the ESP32 with Arduino IDE, including projects, tips, and tricks! The registrations are open, so

The content is intended to be updated from time to time, I will add more details if I found new display or library update. You can also help me enrich the content by leaving comments below.

You can run various IoT projects prefectly without any display. But not all IoT project only feed data in single direction (IoT to server), some IoT also gather real time information from the server for displaying.

My previous instructables, ESP32 Photo Clock is am example, it download a current minute photo from the Internet, decode the JPEG photo and display it.

Many Arduino projects use monochrome display, one of the reason is the limited resources of a MCU. 320 pixels width, 240 pixels height and 8 bits color for each RGB color channel means 230 KB for each full screen picture. But normal Arduino (ATmega328) only have 32 KB flash and it is time consuming (over a second) to read data from SD card and draw it to the color display.

ESP32 have changed the game! It have much faster processing power (16 MHz vs 240 MHz dual core), much more RAM (2 KB vs over 200 KB) and much more flash (32 KB vs 4 MB), so it is capable to utilize more color and higher resolution image for displaying. At the same time it is capable to do some RAM hungry process such as Animated GIF, JPEG or PNG file decoding, it is a very important feature for displaying information gathered from the internet.

Color display have many type of interfaces: Serial Peripheral Interface (SPI), 6-bit, 8-bit, 16-bit, 18-bit and 24-bit parallel interfaces and also NeoPixel!

SPI dominate the hobby electronics market, most likely because of fewer wire required to connect. Most display in my drawer only have SPI pins breaking out, so this instructables focus on SPI display and a few 8-bit display.

NeoPixel matrix is a very special type of color display. If you are interested in NeoPixel matrix display, here are some of my instructables using it:

There are various color display for hobby electronics: LCD, IPS LCD, OLED with different resolutions and different driver chips. LCD can have higher image density but OLED have better viewable angle, IPS LCD can have both. OLED have more power efficient for each light up pixel but may have burn-in problems. Color OLED operate in 14 V, it means you need a dedicate step-up circuit, but it is not a problem if you simply use with a break-out board. LCD in most case can direct operate in 3.3 V, the same operating voltage as ESP32, so you can consider not use break out board to make a slimmer product.

Software support on the other side also influence your selection. You can develop ESP32 program with Arduino IDE or direct use ESP-IDF. But since ESP-IDF did not have too much display library and not much display hardware supported, so I will concentrate on Arduino display libraries only.

For the beginner, I think buying adafruit, or similar supportive vendor, hardware and using its Arduino library can have good seamless experience (though I have no budget to try it all). TFT_eSPI library have better performance but configuration require make changes in the library folder. Ucglib and UTFT-ESP run a little bit slow but it support many hardware and it is a popular library, you can find many Arduino projects using it. LovyanGFX library start appear at 2019, it support many dev device such as M5Stack, M5StickC, TTGO T-Watch, ODROID-GO, ESP-WROVER-KIT, WioTerminal and more. I am also writing a new library called Arduino_GFX since 2019.

OLED have a big advantage, the pixel only draw power if it lights up. On the other hand, LCD back light always draw full power even you are displaying a black screen. So OLED can help save some power for the project powered by a battery.

Thanks for the popularity of wearable gadget, I can find more small size IPS LCD in the market this year(2018). The above picture is an 0.96" 80x160 IPS color LCD using ST7735 driver chip. As you can see in the 3rd picture, you can treat it as a 128x160 color display in code but only the middle part is actually displaying. The 4th picture is the display without breakout board, it is thin, tiny and very fit for a wearable project!

SSD1283A is 1.6" 130x130 display, it claim only consume 0.1 in sleep mode and backlight turned off. In sleep mode the last drawn screen still readable under sufficient lighting.

ST7789 also a common driver chip in ESP32 community. One of the reason is ESP32 official development kit using it. As same as ILI9341, ST7789 also can drive 240x320 resolution.

This also the highest pixel density color display in my drawer. As same as normal LCD, it can direct operate in 3.3 V, so it is very good for making slim wearable device.

There are many display libraries that can support various hardware. I have picked 4 of most popular Arduino library for comparison:Adafruit GFX Family

The display speed is one of the most important thing we consider to select which library. I have chosen TFT_eSPI PDQ test for this comparison. I have made some effort to rewrite the PDQ test that can run in 4 libraries. All test will run with the same 2.8" ILI9341 LCD.

As I found TFT_eSPI is the most potential display library for ESP32 in this instructables, I have paid some effort to add support for all my display in hand. The newly added display support marked letter M in red at the above picture, here is my enhanced version:

Adafruit sell various display module in hobby electronics market and they also have very good support in software level. Their display libraries all built on a parent class called Adafruit_GFX, so I call it Adafruit GFX Family. This library generally support most Arduino hardware (also ESP32).

In Arduino Library Manager simply search "adafruit display", you can see all the family members. If you want to install it, say ILI9341, simply select "Adafruit ILI9341" and then click install. Remember also install its dependent library "Adafruit GFX Library".

This library method signature is very similar to Adafruit GFX, but it is tailor-made for ESP8266 or ESP32. I think the source code is optimised for ESP32, so the PDQ result is much faster than other libraries.

Note: The most difficult part using this library is you are required to configure this library before you can use it. The configuration file is located at the library folder, it should be "Arduino/libraries/TFT_eSPI/User_setup.h" under you own documents folder. It have many comments help you to do that, please follow the comments step by step to finish the configuration. Here is my User_setup.h for ILI9341:

ESP32 + ILI9341 can run at SPI speed 40 MHz, it require some code change at library folder. The above pictures are the fine tuned result. Here are the code change summary:

ST7735 and ILI9341 are the most popular display, this 2 are better option for the beginner. You may notice LCD have a big weakness, the viewable angle, some color lost outside the viewable angle and the screen become unreadable. If you have enough budget, OLED or IPS LCD have much better viewable angle.

In most case, we study how to use a code library by searching sample on the web. I have tried search four libraries keyword in Github, Adafruit is most popular and UTFT the second.

ILI9341 should be most valuable display for the beginner. Adafruit GFX Library should be most easy to use for the beginner, and since TFT_eSPI have very similar method signature, it is very easy to switch to a faster library later on.

OLED require 14 V to light up the pixel so it is not easy to decouple the breakout board. On the other hand, LCD (also IPS LCD) usually operate in 3.3 V, as same as the ESP32. In most case, there are only the LED control circuit required between LCD and ESP32, i.e. a transistor and few resistors. So it relatively easy to make it.

If you read through the data sheet of the color display, you may find most of color display can support 18 bit color depth (6 bit for each RGB channel). 18 bit color depth can have a better image quality that 16 bit color depth (5 bit in red and blue channel, 6 bit for green channel). However, only Ucglib actually run at 18 bit color depth (262,144 colors), other 3 libraries all run at 16 bit color depth (65,536 colors). It is because 18 bit color depth actually require transfer 3 bytes (24 bit) of data for each pixel, it means 50% more data require to transfer and store in memory. It is one of the reason why Ucglib run slower, but it can have a better image quality.

Thank you very much for posting this detailed review of the color display option available for "Duino users. You have saved me hours, maybe days of time wandering the web looking for information.0

Great article! Very interested in round displays. There are available round displays based on st7687s (128 * 128) and st7789 (240 * 240), but I have not found any information on practical use.

Hello! Yes, I purchased this display from keyestudio, connected it to esp32 using this library from dfrobot. It is only necessary to consider that the pinout of the display connectors differs from dfrobot and keyestudio.

I"m wanting to connect a VGA camera, the sort you find as a little module on eBay with OVPxxxx chip, to a screen such as ILxxxx family, which appears to have direct VGA input. I think it will work if I connect the camera directly with no MCU, but I"d also like to add a cross-hair to the display (for a drill targetting system). I wonder is it possible to intercept the serial video data and change individual pixels in a streaming fashion, instead of loading a whole screen into memory, changing it and passing it on? I ask because it seems to me it would need a much less powerful MCU.0

Thank you so much for such a great article. I have been trying to choose the best library to use for a project that will use either a SSD1351 or a ST7735 both being 128x128. The key to my project is to be able to dump a frame buffer in to the display and then recalculate the next frame buffer. :)

Those 2 pins must be dedicated to the display, otherwise the display will get confused without the CS pin. One DAT/CLK to LCD and another DAT/CLK to I2C.

Hello! Thank"s for your instruction. I want to use your 8pin ili9486 320x480 spi display with one of your presented libraries and esp32. 1.) Could you please tell me the connections between the display and the esp32 and 2.) which numbers do I have to write into the line utft myglcd (ili9486,?,?,?,?)?

I have updated the arduino IDE to 1.8.9 and ESP32 boards as per instructions, but cant find the problem. If you have any ideas I really appriecate it.

Hi Dan, yes I took Sara’s advice and selected the correct camera module in the code but commenting out the ones that don’t apply. I did also find reducing the upload speed made things more stable. I think my programmer is not the best.

Hi Dan, did you found the solution. I also purchase two units with different brand with same issue. (the first one have successed before but when retry to reupload the issue came).

Any way you know of to see the video stream or stills via a TFT display on another ESP through web browser or otherwise? I’ve used ESPNow between ESP12’s or 32’s for display of thermal cam images but they’re much smaller. Avoids need for phone or laptop tied up….

Alternatively, if you have the latest updated ESP32 add-on, you should have the code in your examples. Go to File > Examples > ESP32 > Camera and open the CameraWebServer example.

I was looking for something like this for my recent project, Thanks! Great tutorial! But I think ESP32-CAM is “unofficial” combination of ESP32 with a camera. I think Espressif themselves released a dedicated “official” ESP32+camera board called ESP-EYE with their own “official” software library called ESP-WHO.

We haven’t fully tested the ESP-EYE yet. We’ve played with the example firmware that they provide and we made a blog post about it that you can read here: https://makeradvisor.com/esp-eye-new-esp32-based-board/

Try to check the cable, connections, power source … etc. If you can, try to measure the voltage that goes directly to the pins on the ESP32CAM board. It should be the closest to 5 Volt.

Thanks, it will be of great help, recently I was able to integrate my esp32 cam into an MQTT client library, every face detected a publisher is sent to the broker

I’ve selected AI Thinker in the code and reduced the upload to 115200. Anyone have some insights? I have a M5Stack Camera which works pretty well with the code but these two are dead.

There is a small red led (GPIO33 inverted) . The main led is controlled by GPIO4. In the example CamWebServer program there is AFAIK no possibility in the webserver to switch the main LED.

That occurs selecting AI Thinker. The other two options give me the 0x20001 error. I bought the esp camera from DIYMORE.CC. The description in their ad prints AI Thinker on the chip, but my actual device does not have AI Thinker printed. It just has DM-ESP32-S.

Then the web service did not appear in google chrome browser. Error message was something about too much header lines or so. In MS Edge it was ok. But i have no image from the cam. Cam must be broken. So i have to wait another month to get this as spare part. Have also ordered another ESP board with an external antenna hoping to get better connection to the router.

The brownout detector error usually means that the ESP32 is not being powered properly. You can read more about this on our troubleshooting guide, bullet 8: https://randomnerdtutorials.com/esp32-troubleshooting-guide/

The ESP32-CAM should work fine being powered either with 3.3V through the 3.3V pin or 5V through the 5V pin. You’re probably not providing enough current.

Thank you very much for sharing. Using M5STACKcam I didn’t had image. After troubleshooting and comparing with other codes I changed setting for Y2_GPIO_NUM to 17. Now it works like a sharm
