P-NUCLEO-IHM001  

The STM32 Nucleo pack P-NUCLEO-IHM001 is a kit composed of: the X-NUCLEO-IHM07M1 board, the NUCLEO-F302R8 board and the motor (refer to the first figure on the cover page).

The STM32 Nucleo pack P-NUCLEO-IHM002 is a kit composed of: the X-NUCLEO-IHM07M1 board, the NUCLEO-F302R8 board, the motor and the DC power supply (refer to both figures on the cover page).

This platform provides a motor control solution for three-phase, low-voltage and low-current DC brushless motor. It is based on the L6230 driver (belonging to STSPIN family) and on the STM32F302R8 MCU.

The L6230 driver is a DMOS fully integrated device for three-phase brushless PMSM motor, with integrated overcurrent and thermal protection.The STM32F302R8 is a 32-bit microcontroller based on a high-performance ARM^®Cortex^®-M4 32-bit RISC core, with floating point unit (FPU), operating at a frequency of up to 72 MHz and embedding an advanced analog peripheral set.

The X-NUCLEO-IHM07M1 board is fully configurable and ready to support different closed loop control, FOC or 6-step, based on sensorless or sensor mode. It is compatible with three shunts or single shunt for current sense measuring.

The NUCLEO-F302R8 board provides an affordable and flexible way for users to try out new concepts and to build prototypes with STM32 MCU. It does not require any separate probe as it integrates the ST-LINK/V2-1 debugger and programmer.

Only for the P-NUCLEO-IHM002 pack the included power supply unit provides the appropriate power.
