X-NUCLEO-IHM06A1 Low voltage stepper motor driver expansion board based on the STSPIN220 for STM32 Nucleo Data brief 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. Features Low voltage range: 1.8 to 10 V Microstep adjustment up to the 256th step Phase current: up to 1.3 ARMS Current control with adjustable off-time Full protection overcurrent and short circuit protection Thermal shutdown Compatible with Arduino UNO R3 connector Compatible with STM32 Nucleo boards RoHS compliant June 2016 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.
