Getting started with the high power stepper motor driver
expansion board based on powerSTEP01 for STM32 Nucleo
Introduction
The X-NUCLEO-IHM03A1 is a high power stepper motor driver expansion board based on the
powerSTEP01. It provides an affordable and easy-to-use solution for driving high power bipolar stepper
motors in your STM32 Nucleo project. The fully digital motion control through speed profile generation,
dynamic positioning feedback and a complete suite of protection features offer high levels of
performance and robustness The X-NUCLEO-IHM03A1 is compatible with the Arduino UNO R3
connector and supports the addition of other boards which can be stacked to drive up to three stepper
motors with a single STM32 Nucleo board.
