Description
The X-NUCLEO-IHM04A1 is a dual brush DC
motor drive expansion board based on the L6206
(DMOS dual full bridge driver) to drive dual
bipolar DC or quad unipolar DC motors. It
provides an affordable and easy-to-use solution
for driving DC motors in your STM32 Nucleo
project. 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.
