Description
The X-NUCLEO-IHM16M1 motor driver expansion board is based on the STSPIN830
monolithic driver for three-phase brushless motors.
It represents an affordable, easy-to-use solution for driving brushless motors in your
STM32 Nucleo project, implementing single and three-shunt current sensing.
The STSPIN830 embeds a PWM current limiter with adjustable threshold together
with a full set of protections.
The X-NUCLEO-IHM16M1 expansion board is compatible with the Arduino and ST
morpho connectors, so it can be plugged to an STM32 Nucleo development board
and stacked with additional STM32 Nucleo expansion boards.
