Description

The X-NUCLEO-IHM01A1 is a stepper motor

driver expansion board based on the L6474.

It provides an affordable and easy-to-use solution

for driving a stepper motor in your STM32 Nucleo

project.

The advanced current control of the L6474 and a

complete set of protection features offer high

levels of both performance and robustness.

The X-NUCLEO-IHM01A1 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.
