Getting started with the X-NUCLEO-IHM04A1 dual brush DC
motor driver expansion board for STM32 Nucleo
Introduction
The X-NUCLEO-IHM04A1 is a dual brush DC motor drive expansion board based on L6206 (DMOS
dual full bridge driver) to drive dual bipolar DC or quad unipolar DC motors. It provides a low cost,
robust and easy-to-use solution for driving DC motors in your STM32 Nucleo project. A flexible solution
for driving 1 to 4 DC motors is implemented via jumpers.
The X-NUCLEO-IHM04A1 is compatible with the Arduino UNO R3 connector, and supports the addition
of other expansion boards with a single STM32 Nucleo board. The user can also mount the ST Morpho
connector.
