STMicroelectronics Stepper Motor Driver Expansion Board Motor Driver for X-NUCLEO-IHM14A1 for STM32 Nucleo, Arduino Uno

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.
