Description
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.
