Quick Overview
The DIYables 2.8 Inch ESP32 Display combines an ESP32-WROOM-32 development board and a 240x320 resistive touchscreen on a single PCB, so a complete WiFi connected user interface works out of the box without extra wiring. The dual-core ESP32-WROOM-32 module runs at up to 240MHz with 520KB SRAM, 448KB ROM, and 4MB flash memory, leaving plenty of headroom for graphics, network code, and sensor logic at the same time.
The display is driven by an ILI9341 controller at 240x320 resolution with 16-bit RGB 65K full color output, giving crisp menus, gauges, charts, and icons, while the resistive touch panel adds direct on screen input for buttons and menu navigation. Onboard circuits handle LCD backlight control, touch control, speaker drive, a photosensitive light input, and RGB LED control. Expansion is covered by a TF card slot, a serial port, a sensor port with 3.3V and two GPIO pins for I2C, DHT11 and other sensors, and reserved IO pins for extra sensors and modules. Programs can be developed with Arduino IDE, ESP-IDF, MicroPython, or Mixly, with one-click program download plus compatible libraries and sample programs.
Ideal for smart home control panels, IoT dashboards, weather stations, data loggers, handheld instruments, HMI touch interfaces, and any project that needs a color touchscreen with WiFi and Bluetooth already built in.
