esp8266 2.4 tft lcd price

Even though it might not be visible at first sight, there’s a tremendous amount of work behind this thing (and by ‘thing’ is meant a combination of software and hardware). When you start installing the sample Weather Station sketch, it appears that you need to install some libraries, all of them by Daniel Eichhorn: ESP8266 WeatherStation which is a WeatherUnderground client, Json Streaming Parser that helps keeping low memory profile while getting huge API responses, and Mini Grafx library that implements a VSYNC equivalent through framebuffer for embedded devices.

The ILI9341 TFT module contains a display controller with the same name: ILI9341. It’s a color display that uses SPI interface protocol and requires 4 or 5 control pins, it’s low cost and easy to use.

The resolution of this TFT display is 240 x 320 which means it has 76800 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).

The ILI9341 TFT display board which is shown in project circuit diagram has 14 pins, the first 9 pins are for the display and the other 5 pins are for the touch module.

Pins D5 (GPIO14) and D7 (GPIO13) are hardware SPI module pins of the ESP8266EX microcontroller respectively for SCK (serial clock) and MOSI (master-out slave-in).

The first library is a driver for the ILI9341 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “ili9341” and choose the one from Adafruit).

The ILI9341 TFT display is connected to NodeMCU hardware SPI module pins (clock and data), the other pins which are: CS (chip select), RST (reset) and DC (data/command) are defined as shown below:

In the previous article (“WiFi OLED Mini Weather Station with ESP8266“) I have used the OLED kit from https://blog.squix.org. And as promised, this time it is about the “ESP8266 WiFi Color Display Kit”:

I had ordered both because I thought that the Color Display kit is needs the other kit as a base. Well, it turned out that both kits work independently. My bad. Actually this is good, as I have now two independent ESP8266 weather stations :-). An addition to that, they can exchange data (e.g. temperature/humidity) with a server, so that makes them a perfect dual weather station.

Example code is available on GitHub (https://github.com/squix78/esp8266-weather-station-color). The code is very well documented I had no issues to make all the needed configuration (WiFi SSID and connection settings). After a few  hours I had the ESP8266 weather station up and running in the first prototype of the enclosure:

After a few hours, I have now my second ESP8266 WiFi weather station with touch LCD. It is not looking good and I very much enjoy it. The design is available on Thingiverse (https://www.thingiverse.com/thing:2527282).

It is a 2.0 inch TFT display module.TFT liquid crystal has a semiconductor switch for each pixel,and each pixel can be directly controlled by dot pulses,so each node is relatively independent and can be continuous...

ESP8266 and ESP32 work far better with SPI Displays. No need for level shifters. And you still have spare pins for actually doing something with external sensors / electronics.

The code in this project supports an ILI9341 240x320 TFT display with code running on an ESP8266. To get you up and running in no time we created a kit which contains all the necessary parts including a custom PCB to connect display and WiFi chip:

The IoD-09 modules feature a full colour 0.9” TFT LCD display. They are powered by the WiFi enabled ESP8266, which offers an array of functionality and options for any Designer / Integrator / User.
