Quick Overview
This DIYables 2.8 inch TFT LCD display module uses the ST7789 driver chip with a 240x320 pixel resolution and 65K color depth, delivering crisp, colorful graphics over a simple 4-wire SPI interface. The module operates on both 3.3V and 5V logic, making it fully compatible with 3.3V ESP32 boards and 5V Arduino boards without additional level shifting on most signal lines.
The board measures 82mm x 50mm and includes an onboard microSD card slot on the back for additional storage of images, fonts, or logged data, alongside the standard SPI pin header (VCC, GND, SCK, SDI/MOSI, SDO/MISO, DC, RESET, CS). A DIYables TFT SPI library and step-by-step tutorials are included to help you get up and running quickly with Arduino, ESP32, ESP8266, and Raspberry Pi.
This display is well suited for instrument panels, weather stations, IoT dashboards, wearable devices, robotics displays, and human-machine interface (HMI) projects that need a compact, colorful graphical screen.

※ NOTE THAT:
This display operates at 3.3V logic. When using 5V boards (Arduino Uno, Nano, Mega, Uno R4), add a 5V → 3.3V level converter on the MCU-driven signal lines (MOSI, SCK, CS, DC, RST). The MISO line (display → MCU) does not require conversion.
