The X-NUCLEO-IHM03A1 is an high power stepper motor driver expansion board based on 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, adding positioning calculations and a complete set of protection features, offers 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.
