Getting started with the X-NUCLEO-IHM13A1 low voltage dual brush
DC motor driver
expansion based on STSPIN250 for STM32 Nucleo
Introduction
The X-NUCLEO-IHM13A1 is a low voltage brush DC motor driver expansion board based on the
STSPIN250 for STM32 Nucleo.
It provides an affordable and easy-to-use solution for the implementation of portable motor driving
applications such as thermal printers, robotics and toys.
The X-NUCLEO-IHM13A1 is compatible with the Arduino UNO R3 connector and most STM32 Nucleo
boards.

2 Getting started
The X-NUCLEO-IHM13A1 expansion board is a DC motor driver covering a wide range of
applications.
The maximum ratings of the expansion board are:
•Power stage supply voltage (VS) from 1.8 to 10 V
•Motor phase current up to 2.6 A rms.
To start your project with the expansion board:
1. Check the jumper position based on your configuration (see Section 3.2: "Selecting
reference voltage").
2. Connect the X-NUCLEO-IHM13A1 to the STM32 Nucleo board through Arduino UNO
R3 Connectors (CN5, CN6, CN8 and CN9).
3. Supply the board through the input 1 (Vin) and 2 (GND) of the connector J1. The D3
(red) LED will turn on.
4. Develop your application using the examples provided with the firmware library (X-
CUBE-SPN13).
