L6470
Two axis stepper motor driver expansion board
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
Order Code: X-NUCLEO-IHM02A1

Software Overview 11
X-CUBE-SPN2 Software description
•The X-CUBE-SPN2 is an expansion software package for
STM32Cube. The software runs on the STM32 and includes
drivers that initialize and send application commands to all stepper
motor drivers (L6470) mounted on one or more dedicated STM32
expansion board (X-NUCLEO-IHM02A1) stacked on a STM32
Nucleo Board.
•It is compatible with the NUCLEO-F401RE, the NUCLEO-F302R8
or the NUCLEO-F072RB when connected to X-NUCLEO-IHM02A1
expansion board for STM32.
Key features:
•Complete middleware to build applications using stepper motor
driver (L6470) for STM32 expansion board (X-NUCLEO-
IHM02A1)
•Addresses more than one STM32 expansion board
•Addresses more than two stepper motor drivers in the same
daisy chain
•Simply functions to send application commands from one to all
stepper motor drivers in a daisy chain simultaneously
•Sample application to send commands through a PC via
USART
•Easy portability across different MCU families, thanks to
STM32Cube
•Free, user-friendly license terms
•Sample implementation available on board X-NUCLEO-
IHM02A1 when plugged into NUCLEO-F401RE, NUCLEO-
F302R8 or NUCLEO-F072RB
