Getting started with X-NUCLEO-IHM02A1; two-axis stepper motor
driver expansion board based on L6470 for STM32 Nucleo
Introduction
The X-NUCLEO-IHM02A1 is a two-axis stepper motor driver expansion board based on
L6470. It provides an affordable and easy to use solution for driving low voltage motor
control for stepper motors in your STM32 Nucleo project. The expansion board includes two
L6470 fully integrated micro stepping motor drivers for motor stepper control throughmotors
high-end motion control commands received via SPI. It is able to drive one or two stepper
motors when plugged on an STM32 Nucleo board. This board is equipped with an
Arduino™ UNO R3 connector and the layout is also compatible with ST morpho connectors.
One or more of these expansion boards can be plugged on a STM32 Nucleo board to
control one or more stepper motorss. The SPI peripherals from each L6470 are connected
in daisy chain configuration.
