The X-NUCLEO-IHM02A1 is a two axis stepper motor driver expansion board based on the L6470. It provides an affordable and easy-to-use solution for low voltage motor control driving for stepper motors in your STM32 Nucleo project. The expansion board includes two L6470s, a fully-integrated micro stepping motor driver used to control stepper motors by means of high-end motion control commands received through SPI. It is capable of driving one or two stepper motors when plugged into an STM32 Nucleo board.
