Getting started with the STEVAL-SPIN3202 evaluation board,
advanced BLDC controller with embedded STM32 MCU
Introduction
The STEVAL-SPIN3202 3-phase brushless DC motor driver board is based on the STSPIN32F0A 3-
phase controller with integrated STM32 MCU.
It implements a single shunt resistor current reading topology and provides an easy-to-use solution for
device evaluation in different applications such as home appliances, fans, drones and power tools.
The board is designed for the sensored or sensorless six-step algorithm and Field Oriented Control with
single shunt current sensing.
