Getting started with X-NUCLEO-IHM08M1 low-voltage BLDC motor
driver expansion board based on STL220N6F7 for STM32 Nucleo
Introduction
The X-NUCLEO-IHM08M1 is a three-phase brushless DC motor driver expansion board based on
STripFET™ F7 Power MOSFET STL220N6F7 for STM32 Nucleo. It provides an affordable and easy-to-
use solution for driving a three-phase brushless DC motor in your STM32 Nucleo project. The X-
NUCLEO-IHM08M1 is compatible with the ST morpho connector and supports further stacking of
additional boards on a single STM32 Nucleo board. You can also mount the Arduino™ UNO R3
connector.
The X-NUCLEO-IHM08M1 is fully configurable and ready to support different closed loop control
scenarios based on sensorless or sensor mode control, and it is compatible with three-shunt or single-
shunt current sense measuring. The L6398 IC driver used on this STM32 Nucleo expansion board is a
single-chip half bridge gate driver for the N-channel power MOSFET. This combination of the L6398
gate driver and the STL220N6F7 Power MOSFET forms a high current power platform for BLDC
motors, while the digital section supported by the STM32 Nucleo board allows for a 6-step or FOC
control algorithm solution, which you can select via the firmware. This document describes how to
configure the X-NUCLEO-IHM08M1 expansion board to operate with STM32 Nucleo board.
