Getting started with X-NUCLEO-IHM06A1 low voltage stepper motor
driver expansion board based on STSPIN220 for STM32 Nucleo
Introduction
The X-NUCLEO-IHM06A1 is a low voltage stepper motor driver expansion board based on the
STSPIN220 monolithic low voltage driver for low voltage stepper motors. It represents an affordable,
easy-to-use solution for driving low voltage stepper motors in your STM32 Nucleo project, implementing
portable motor driving applications such as thermal printers, robotics and toys.
It includes a stepper driver able to operate in low voltage (battery) scenarios, allowing zero consumption
states. The device implements current control with fixed OFF time and a maximum 1/256 microstep
resolution.
The X-NUCLEO-IHM06A1 is compatible with the Arduino UNO R3 connector and supports the addition
of other STM32 expansion boards with a single STM32 Nucleo board. You can also mount the ST
morpho connector.
