Getting started

The X-NUCLEO-IHM03A1 expansion board is a high power stepper motor driver covering

a wide range of applications. In particular, the maximum ratings of the board are the

following.



Power stage supply voltage (VS) from 10.5 V to 50 V



Motor phase current up to 10 A r.m.s.

Follow this sequence to start your project with the board:

1.

Check the jumper position based on your configuration (see Section 2: "Hardware

description and configuration").

2.

Plug the board to the STM32 Nucleo board through Arduino UNO R3 for the X-

NUCLEO-IHM03A1.

3.

Supply the board through the input 1 (VS) and 2 (ground) of the connector CN1. The

power OK (green) and fault (red) LEDs will turn on.

4.

Develop your application using the examples provided with the firmware library, X-

CUBE-SPN3, high power stepper motor driver software expansion for STM32Cube.

Further support material is available on the powerSTEP01 (www.st.com/powerstep)

and STM32 Nucleo web pages (www.st.com/stm32nucleo).

Up to three expansion boards can be stacked on the same STM32 Nucleo board

as described in Section 2.2: "Multi-motor configuration".
