Wyświetlacz LCD TFT 1.28" 240x240 okrągły SPI 8-pin GC9A01 IPS do Arduino

Round LCD TFT IPS display module 1.28"

A compact colour round LCD module with a 1.28 inch diagonal and 240 × 240 pixel resolution. The screen uses the capable GC9A01 driver and IPS technology for wide viewing angles and accurate colour reproduction. The panel is mounted on a PCB fitted with four mounting holes for easy integration into your device. The module communicates via the SPI interface and suits microcontroller-based projects. It is compatible with popular platforms including Arduino, ESP8266, ESP32, and Raspberry Pi.
