X-NUCLEO-IHM06A1

The X-NUCLEO-IHM06A1 is a low voltage stepper motor driver expansion board based on the STSPIN220 for STM32 Nucleo. It represents an affordable, easy to use solution for driving low voltage stepper motors in 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 Arduino UNO R3 connector and supports the addition of other STM32 expansion boards with a single STM32 Nucleo board. Can also mount ST morpho connector.
