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 256
th
step.
The X-NUCLEO-IHM14A1 expansion board is
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.
