Getting started with the X-NUCLEO-IHM12A1 low voltage dual brush
DC motor driver expansion based on STSPIN240 for STM32 Nucleo
Introduction
The X-NUCLEO-IHM12A1 is a low voltage dual brush DC motor driver expansion board based on the
STSPIN240 for STM32 Nucleo.
It provides an affordable and easy-to-use solution for the implementation of portable motor driving
applications such as thermal printers, robotics and toys.
Thanks to its programmable current limiter and complete set of protection features, it offers high levels
of performance and robustness.
The X-NUCLEO-IHM12A1 is compatible with the Arduino UNO R3 connector and most STM32 Nucleo
boards.
