The RoundyPi is a round LCD display based on the popular RP2040 (the same chip used in the Raspberry Pi Pico!) along with a compact 1.28" LCD display with a 240×240 resolution and 65K RGB colour.
The RoundyPi comes with an embedded GC9A01 driver and SPI interface that minimise the number of pins consumed by the display.
A micro-USB port is onboard for programming and power, whilst a handy MicroSD card slot has been added for storage.
We also stock the RoundyFi - a variation of this board which uses the popular ESP8266 with Wifi!
