  • The X-NUCLEO-IHM03A1 is an high power stepper motor driver expansion board based on powerSTEP01. It provides an affordable and easy-to-use solution for driving high power bipolar stepper motors in your STM32 Nucleo project. The fully digital motion control through speed profile generation, adding positioning calculations and a complete set of protection features, offers high levels of performance and robustness. 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.

    Key Features

    • Power system-in-package, integrated dual full-bridge with low RDS(on)
    • Voltage range from 10.5 V to 85 V
    • Phase current up to 10 A rms
    • Power OK and fault LEDs
    • Up to 1/128 micro-stepping
    • Programmable speed profile and overcurrent protection
    • Sensorless stall detection
    • Adjustable output slew rate
    • Overtemperature protection
    • Compatible with Arduino UNO R3 connector
    • Compatible with STM32 Nucleo boards
    • Suitable for multi-motor solution
    • RoHS compliant
