The ESP32 Dev Board WiFi Bluetooth with 2.8 inch 240×320 Display TFT Touchscreen CYD has become known in the maker community as the “Cheap Yellow Display” or CYD for short. This development board, whose main chip is an ESP32-WROOM-32 module, comes with a 2.8-inch with a resolution of 240×320 TFT touchscreen LCD, a microSD card interface, an RGB LED, and all the required circuitry to program and apply power to the board.
Furthermore, the board includes a backlight control circuit, touch control circuit, speaker drive circuit, photosensitive circuit, and RGB-LED control circuit. It also provides a TF card slot, serial interface, DHT11 temperature and humidity sensor interface, and additional IO ports.
This is a very versatile board to build GUIs for your IoT projects and is much more convenient and practical than using a separate ESP32 board with a TFT screen.
