Hardware Overview - ST X-NUCLEO-IHM14A1 Quick Start Manual

Low voltage stepper motor driver expansion board
X-NUCLEO-IHM14A1 Hardware Description
•
The X-NUCLEO-IHM14A1 motor driver expansion
board is based on the STSPIN820 monolithic driver
for stepper motors.
•
It represents an affordable, easy-to-use solution for
driving stepper motors in your STM32 Nucleo project,
implementing motor driving applications such as
2D/3D printers, robotics and security cameras.
•
The STSPIN820 implements a PWM current control
with constant OFF time adjustable via an external
resistor and a microstepping resolution up to the
256th step.
•
The X-NUCLEO-IHM14A1
compatible with the Arduino UNO R3 connector and
the ST morpho connector, so it can be plugged to the
STM32 Nucleo development board and stacked with
additional X-NUCLEO expansion boards.
