PicoPU.
CZ
A GPGPU built from RP2350 MCUs.

Open-source GPGPU

A graphics processor made of many small microcontrollers.

PicoPU is a very simple open-source general purpose graphics processing unit that uses RP2350 MCUs as its compute cores. It is made of three parts: host drivers, GPU firmware and the PCB hardware.

The project is very much work in progress.
