The STEVAL-SPIN3201 board is a 3-phase brushless DC motor driver board based on the STSPIN32F0, a 3-phase controller with an integrated STM32 MCU, and implements 3-shunt resistors as current reading topology.It provides an easy-to-use solution for the evaluation of the device in different applications such as the home appliance, fans, drones and power tools.
The board is designed for the sensored or sensorless field-oriented  control algorithm with3-shunt sensing.

• The STEVAL-SPIN3201 provides a complete 3-shunt FOC solution composed by an STSPIN32F0 - advanced BLDC controller with an embedded STM32 MCU - and a triple half-bridge power stage with the NMOS STD140N6F7.
• The STSPIN32F0 autonomously generates all the required supply voltages: the internal DC/DC buck converter provides 3V3 and an internal linear regulator provides 12 V for the gate drivers.
• The current feedback signal conditioning is performed through three of the operational amplifiers embedded into the device and an internal comparator performs overcurrent protection from shunt resistors.
• Two user buttons, two LEDs and a trimmer are available to implement simple user interfaces (e.g. starting/stopping the motor and set target speed).
• The STEVAL-SPIN3201 board supports the quadrature encoder and digital Hall sensors as motor position feedback.
• The board includes an ST-LINK-V2 allowing the user to debug and download firmware without any extra hardware tool.
