1.28" 240x240 TFT IPS round colour display GC9A01, round PCB, SPI

Product detailed description

A round colour LCD display with a 1.28" diagonal and 240 × 240 px resolution utilises the GC9A01 controller and an IPS panel, offering faithful colours and a clear image from practically any angle. The display is mounted on a round PCB with a pin header, meaning the board shape mirrors the display area, allowing the module to be easily integrated into smartwatches, alarm clocks, tachometers, panel gauges, or decorative projects. Communication takes place via a four-wire SPI bus, meaning only a few wires are needed to connect it to an Arduino, ESP32, or Raspberry Pi.
