Inspired by SimpleFOC shield, the tiny version was designed and built. The board is an Arduino-based brushless controller that has an on-board magnetic encoder (AS5600) and an on-board microcontroller. The tiny board is a fully integrated tiny solution for brushless-based actuators, similar to Dagor-Brushless-Controller, but at a lower cost.
