Stepper motor driver expansion board based on L6474 for
STM32 Nucleo
Introduction
The X-NUCLEO-IHM01A1 is a stepper motor driving board based on the L6474.
It provides an affordable and easy-to-use solution for driving stepper motors in your STM32 Nucleo
project.
The advanced current control of the L6474 and the complete set of protections guarantee high
performance and robustness.
The X-NUCLEO-IHM01A1 is compatible with the Arduino UNO R3 connector on the ST Morpho
connector.
More boards of the same type can be stacked easily to drive up to three stepper motors with a single
STM32 Nucleo board.
