From the project
The board specific repo of the MicroDev128-32P
The MicroDev128-32P is open-source development board with a high-power voltage regulator with up to 2A continous, Multi-voltage IO - which allows PortC to run on a different voltage than the rest of the board - elimenating the need for voltage level shifters. The MicroDev128-32P aims to be better price to performance ratio than a tradition Arduino Nano. To view the Schematics you can go into the Kicad files folder. All files were made on KiCad 10.04 and should import without other dependencies. The 3D models are all included in the folder.
