Figure 3: X-NUCLEO-IHM07M1 plugged on STM32 Nucleo
The interconnection between the STM32 Nucleo and the X-NUCLEO-IHM07M1 has been
designed for full-compatibility with many STM32 Nucleo boards and no solder bridge
modification is required. When stacked, the system is ready to operate with the connection
of a BLDC/PMSM motor. For proper use, please respect the hardware and software
settings. For the software details, refer to the X-CUBE-SPN7 software expansion
documents available on www.st.com.
