Getting started with the X-NUCLEO-IHM09M1 motor control
connector expansion board for STM32 Nucleo
Introduction
The X-NUCLEO-IHM09M1 is a motor control connector expansion board for STM32 Nucleo. It provides
an easy way to evaluate motor control solutions for three-phase motors by adapting the STM32 Nucleo
board with an external ST motor control power board, thanks to ST morpho and motor control
connector. The 34-pin motor control connector is compatible with all major ST motor control power
boards, requiring an external digital section (MCU) to drive a three-phase motor. The DAC connector
supports user code development and testing with easy access to the MCU peripherals. An LED is
available for fault condition signaling or status indication.
This document describes the procedure for configuring this STM32 NUCLEO expansion board to
operate with the STM32 Nucleo board and run a voltage 3-phase brushless motor. The board is fully
compatible with the ST Six-Step and FOC (field oriented control) firmware library.

Getting started Figure 3: X-NUCLEO-IHM09M1 plugged on STM32 Nucleo The interconnection between the STM32 Nucleo board and the X-NUCLEO-IHM09M1 expansion board is designed for full compatibility with a wide range of STM32 Nucleo boards, with no solder bridge modification required. The stacked solution is ready to operate in connection with a power board compatible with a standard 34-pin flat cable. - Page 6 UM1970 Figure 4: X-NUCLEO-IHM09M1 – top layer with silk-screen The X-NUCLEO-IHM09M1 is equipped with ST morpho connectors - male pin headers (CN7 and CN10), which can be used to connect expansion boards to the STM32 Nucleo board. All signals and power pins of the MCU are available on the STMicroelectronics morpho connector.
