X-NUCLEO-IHM06A1 Low Voltage Stepper Motor Driver

The X-NUCLEO-IHM06A1 is a low voltage stepper motor driver expansion board based on the STSPIN220 monolithic low voltage driver for low voltage stepper motors. It represents an affordable, easy-to-use solution for driving low voltage stepper motors in your STM32 Nucleo project, implementing portable motor driving applications such as thermal printers, robotics and toys.
It includes a stepper driver able to operate in low voltage (battery) scenarios, allowing zero consumption states. The device implements current control with fixed OFF time and a maximum 1/256 microstep resolution.
The X-NUCLEO-IHM06A1 is compatible with the Arduino UNO R3 connector and supports the addition of other STM32 expansion boards with a single STM32 Nucleo board. You can also mount the ST morpho connector.
