STMicroelectronics X-Nucleo-IHM Stepper Motor Driver for STM32 Nucleo Boards / 9064656

X-NUCLEO-IHM03A1 High-Power Stepper Motor Driver Expansion Board. The X-NUCLEO-IHM03A1 is based on powerSTEP01, a system-in-package, integrating a microstepping controller and 10A power MOSFETs in dual full-bridge configuration. The board can drive high power bipolar stepper motors in your STM32 Nucleo project. The fully digital motion control offers high levels of performance and robustness, through speed profile generation, positioning calculations, and a complete set of protection features. The X-NUCLEO-IHM03A1 is compatible with the Arduino UNO R3 connector, and supports the addition of other boards which can be stacked to drive up to three stepper motors with a single STM32 Nucleo board. Operating voltage 7.5V to 85V Adjustable output slew rate Programmable speed profile Up to 1/128 microstepping Sensorless stall detection Integrated voltage regulators SPI interface Low quiescent standby currents Programmable non-dissipative over-current protection Over-temperature protection
