Hardware Overview 10

X-NUCLEO-IHM02A1 Hardware description

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 Motor

in your STM32 Nucleo project. The expansion board includes two

L6470s, a fully-integrated micro stepping motor driver used to control

stepper motors by means of high-end motion control commands

received through SPI.It is capable of driving one or two stepper

motors when plugged into an STM32 Nucleo board.

Main features:

•Nominal operating voltage range: 8 V - 45 VDC

•Maximum output peak current: 7.0 A (3.0 A rms) for each motor

driver

•Digital voltage supply is selectable (3.3 V or 5.0 V)

•USART communication

•SPI interface (may be connected in a daisy chain configuration)

•Equipped with Arduino UNO R3 connectors

•Layout compatible with ST morpho connectors
