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
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.
