Description
The X-NUCLEO-IHM07M1 is a three-phase
brushless DC motor driver expansion board
based on the L6230 for STM32 Nucleo. It
provides an affordable and easy-to-use solution
for driving three-phase brushless DC motor in
your STM32 Nucleo project. The X-NUCLEO-
IHM07M1 is compatible with the ST Morpho
connector and supports the addition of other
boards which can be stacked with onto a single
STM32 Nucleo board. The user can also mount
the Arduino UNO R3 connector. The driver used
on this STM32 Nucleo board is the L6230, a
DMOS fully integrated driver for three-phase
brushless DC motors assembled in a PowerSO-
36 package (L6230PD), with overcurrent and
thermal protection. The L6230 driver is optimized
for six-step and FOC algorithms thanks to
independent current sensing.
