STMicroelectronics P-NUCLEO-IHM03 STM32 Motor Control Development Kit

Develop high-performance three-phase motor control applications with the STM P-NUCLEO-IHM03, featuring STM32 MCU, STSPIN830 FOC driver, and X-NUCLEO-IHM16M1 expansion board.

The STM P-NUCLEO-IHM03 is a complete STM32 motor control development platform designed for three-phase, low-voltage, low-current DC brushless and PMSM motors. It combines the X-NUCLEO-IHM16M1 expansion board, NUCLEO-G431RB MCU board, GBM2804H-100T brushless gimbal motor, and a DC power supply for a fully integrated development solution.

The kit features the STSPIN830 FOC-ready driver in a compact 4x4mm QFN package, integrating control logic with a fully protected low-RDSon triple half-bridge power stage. The X-NUCLEO-IHM16M1 supports 7V - 45V DC operation with up to 1.5A RMS output current and offers overcurrent, short-circuit, and thermal protection.

The NUCLEO-G431RB board is powered by an STM32G431RB MCU (ARM Cortex-M4, 170 MHz) with 128 KB Flash and an onboard STLINK-V3E debugger, supporting single and three-shunt current sensing, sensor-based or sensorless control, and FOC or 6-step algorithms.

Ideal for motor control prototyping, educational projects, and professional development, the P-NUCLEO-IHM03 enables engineers to rapidly design, test, and optimize advanced motor control solutions using STM32 MCUs and industry-standard development tools.
