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.

Getting started
The X-NUCLEO-IHM02A1 expansion board extends the application landscape for STM32
Nucleo board user. It directly handles two-axis stepper motors driving, through the L6470,
and can be used in a wide range of relevant applications.. The maximum ratings of the
L6470 are the following:
•
Power stage supply voltage (VS) from 8 V to 45 V DC;
•
motors phase current up to 3 A r.s.m. (related to the L6470)
To function correctly, the X-NUCLEO-IHM02A1 (two-axis stepper motors driver expansion
board based on L6470) has to be plugged on an STM32 Nucleo board as shown in Figure 2.
Figure 2. X-NUCLEO-IHM02A1 plugged on STM32 Nucleo board
The interconnection between the STM32 Nucleo board and the X-NUCLEO-IHM02A1 is
designed to permit the use of any STM32 Nucleo board. The firmware has been written and
tested for the NUCLEO-F401RE, NUCLEO-F302R8 and NUCLEO-F072RB.
Note:
For correct use of the NUCLEO-F401RE with the X-NUCLEO-IHM02A1, the solder bridge
SB15 on the NUCLEO-F401RE has to be removed (see the NUCLEO-F401RE user manual
for further information).

Multi-motors configuration
It is possible to synchronously drive two-axis stepper motors with one X-NUCLEO-IHM02A1
board only. However, up to four X-NUCLEO-IHM02A1 expansion boards can be stacked on
a single STM32 Nucleo board, so it is possible to drive up to eight stepper motors. Each XNUCLEO-IHM02A1 expansion board is addressable through the nCS pin that must be
connected to one pin only of the microcontroller. So, when using more than one expansion
board, the user must short a different solder bridge among SB7, SB8, SB9 and SB23, for
each X-NUCLEO-IHM02A1. Be sure to align the firmware with any hardware change.

Set-up to try the provided example
Follow this sequence to start your project with the board:
1.
Choose an STM32 Nucleo board from among NUCLEO-F401RE, NUCLEO-F302R8
and NUCLEO-F072RB.
2.
Get the right firmware from the X-CUBE-SPN2 (available on www.st.com) for the
chosen STM32 Nucleo board and program it properly.
–
X-CUBE-SPN2_F401.bin for NUCLEO-F401RE
–
X-CUBE-SPN2_F302.bin for NUCLEO-F302R8
–
X-CUBE-SPN2_F072.bin for NUCLEO-F072RB
3.
Disconnect the STM32 Nucleo board from the PC.
4.
Put a jumper between pin 2 and 3 of J1.
5.
Leave all J2 pins open.
6.
Check the solder bridges meet the default configuration (see Table 3).
7.
Connect two stepper motors to ST1 and ST2.
8.
Stack the X-NUCLEO-IHM02A1 expansion board on an STM32 Nucleo board through
ST morpho or Arduino UNO R3 connectors.
9.
Supply the board through the pin 1 (GND) and 2 (VS) of the connector ST3 with 9.0 V
DC. The green LEDs D1 and D4 will turn on to show each L6470 VREG is on.
10. Connect the STM32 Nucleo board to the PC via USB type A to Mini-B USB cable. The
orange LED D9 will turn on to show the digital voltage is on.
11. The two connected stepper motors will perform a few movements.
Note:
The example is set to use motors such as the hybrid stepping motor 42BYGHM809 by
Wantai Motor. If your motors have different parameters, modify the array named
“MotorParameterInitData” in the “params.c” source file accordingly.
You can now proceed to develop your application using the examples provided with the
firmware library (X-CUBE-SPN2) with yourpreferred IDE among IAR EWARM, Keil MDKARM and Open STM32 SW4STM32.
