Getting started

The X-NUCLEO-IHM01A1 expansion board is a stepper motor driver covering a wide
range of applications.
The maximum ratings are:

Power stage supply voltage (VS) from 8 V to 45 V

Motor phase current up to 3 A rms
To start your project with the board:
1. Check the jumper position in accordance with your configuration (see ).
2. Connect the board to the STM32 Nucleo board with the connector:
a.
b.
Up to three expansion boards can be stacked on the same STM32 Nucleo board, as
described in
1. Supply the board through input 1 (VS) and 2 (ground) of the connector CN1.
2. The power OK (green) and fault (red) LEDs turn on.
3. Develop your application using the examples provided with the firmware library.
Further support material is available on the L6474 (www.st.com/easyspin) and STM32
