RP2350 1.43" AMOLED Round Display Dev Board (466x466)

This compact display development board from Waveshare is controlled by a Raspberry Pi RP2350 and features a round 1.43" AMOLED display with capacitive touch, along with sensors and interfaces to make this a versatile choice for small RP2350 projects. On the front of the unit is the AMOLED display - offering superior contrast (true blacks) and vibrant colours with power efficiency on dark content, because each pixel self-illuminates. It's a 1.43" round display with a 466x466 resolution, offering 16.7 million colours and controlled via SPI. On the rear is where things get even more interesting. You'll find the RP2350 microcontroller backed up with 16MB onboard flash memory, a micro SD slot, 6-axis IMU, RTC with battery header (compatible with Raspberry Pi RTC battery), MX1.25 PicoBlade-compatible lithium battery header with charge circuit, Qwiic-compatible 4-pin I2C header and RESET and BOOT buttons. A USB-C port is provided for power and programming. An optional CNC metal case with real labelling is available - select a variant before adding to your cart. What's Onboard?
