STMicroelectronics Nucleo Pack Motor Controller for L6230, STM32F302R8

P-NUCLEO-IHM002 BLDC Motor Control Development Kit and Power Supply

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. The X-NUCLEO-IHM07M1 is a 3 phase brushless DC motor driver expansion board for STM32 Nucleo, based on L6230 driver with integrated overcurrent and thermal protection.
The NUCLEO-F302R8 board provides an affordable and flexible way for users to try out new concepts and to build prototypes with the STM32 MCUs. The integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and programmer for the STM32, so there is no need for a separate probe.
The STM32F302R8 is a 32-bit analogue and DSP, with Floating Point Unit (FPU), ARM Cortex-M4 microcontroller, operating up to 72 MHz, with 64 KB Flash, 12-bit 5MSPS Analogue-to-Digital Converter, Comparator, and Operational-Amplifier.
The Arduino connectivity support and ST Morpho headers make it easy to expand.
The P-NUCLEO-IHM002 pack includes the DC power supply unit.
