# Arduino *Simple**FOC**Shield* *v3.2*


![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg?color=blue) ![GitHub release (latest by date)](https://img.shields.io/github/v/release/simplefoc/arduino-simplefocshield) ![GitHub Release Date](https://img.shields.io/github/release-date/simplefoc/arduino-simplefocshield?color=blue)

This is an open-source low-cost Brushless DC (BLDC) motor driver board intended primarily for low-power FOC applications up to 5Amps. The board is fully compatible with the Arduino UNO and all the boards with the standard Arduino headers. The *Simple**FOC**Shield*, in combination with the *Simple**FOC**library* provides user-friendly way to control BLDC motors both in hardware and software.
