From the project

hardware to be used with https://github.com/embedded-pro/e-foc

A three-phase brushless (BLDC / PMSM) motor driver board designed to run the e-foc Field-Oriented Control firmware.

This repository contains the KiCad electrical design — schematics, project configuration and (eventually) the PCB layout — for the power and signal-chain hardware that the e-foc control software targets. The microcontroller itself lives on a pluggable module; this board provides the power stage, gate drive, current sensing, protection and peripheral connectivity around it.
