From the project
System on Module based on Microchip PolarFire MPFS250T SoC
This project contains open hardware design files for the Antmicro PolarFire System on Module (SoM) built around Microchip PolarFire MPFS250T RISC-V System on Chip. The SoM exposes two 100-pin high density connectors with signal assignment that is electrically compatible with Raspberry Pi Compute Module 4.
The PCB design files were prepared in KiCad 7.
