Description
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.
