X-NUCLEO-IHM09M1 Motor control connector expansion board for STM32 Nucleo Data brief Description 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. Features ST motor control connector (34 pins) compatible with major ST motor control power boards STM32 Nucleo support, thanks to ST morpho connectors Compatible with six-step and FOC motor control firmware library by ST Debug connector for DAC, GPIOs, etc. Fully populated board conception with test points LED for fault signaling or status indication Potentiometer available (i.e. for speed reference) RoHS compliant October 2015 DocID028547 Rev 1 For further information contact your local STMicroelectronics sales office 1/6 www.st.com Schematic diagram 1 X-NUCLEO-IHM09M1 Schematic diagram Figure 1: X-NUCLEO-IHM09M1 schematic: PWM Figure 2: X-NUCLEO-IHM09M1 schematic: Hall/encoder sensor Figure 3: X-NUCLEO-IHM09M1 schematic: currents Figure 4: X-NUCLEO-IHM09M1 schematic: DAC 2/6 DocID028547 Rev 1 X-NUCLEO-IHM09M1 Schematic diagram Figure 5: X-NUCLEO-IHM09M1 schematic: user interface Figure 6: X-NUCLEO-IHM09M1 schematic: motor control connector DocID028547 Rev 1 3/6 Schematic diagram X-NUCLEO-IHM09M1 Figure 7: X-NUCLEO-IHM09M1 schematic: Arduino UNO R3/ST morpho connector 4/6 DocID028547 Rev 1 X-NUCLEO-IHM09M1 2 Revision history Revision history Table 1: Document revision history Date Version Changes 23-Oct-2015 1 Initial release.
