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. 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).
