A round 1.28-inch display for watch faces, dials and gauges - 240 x 240 pixels in 65K colour on a GC9A01 controller, driven over 4-wire SPI. Seven pins come out along one edge: RST, CS, DC, SDA, SCL, GND and VCC. The circular glass is about 32 mm across and overhangs the board, so it reads as an instrument rather than a screen on a panel. The GC9A01 is well supported by TFT_eSPI, Arduino_GFX and lvgl. Feed it 3.3V logic.
