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

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
