X-NUCLEO-IHM07M1 Three-phase brushless DC motor driver expansion board based on L6230 for STM32 Nucleo Data brief Description Features 3-phase driver for BLDC/PMSM motors Nominal operating voltage range from 8 V to 48 VDC 2.8 A output peak current (1.4 ARMS) Operating frequency up to 100 kHz Non dissipative overcurrent detection and protection Cross-conduction protection Thermal measuring and overheating protection Compatible with STM32 Nucleo boards Equipped with ST Morpho connectors 3-shunt and 1-shunt configurable jumpers for motor current sensing Hall/Encoder motor sensor connector and circuit Debug connector for DAC, GPIOs, etc. Potentiometer available for speed regulation User LED RoHS compliant August 2015 The X-NUCLEO-IHM07M1 is a three-phase brushless DC motor driver expansion board based on the L6230 for STM32 Nucleo. It provides an affordable and easy-to-use solution for driving three-phase brushless DC motor in your STM32 Nucleo project. The X-NUCLEOIHM07M1 is compatible with the ST Morpho connector and supports the addition of other boards which can be stacked with onto a single STM32 Nucleo board. The user can also mount the Arduino UNO R3 connector. The driver used on this STM32 Nucleo board is the L6230, a DMOS fully integrated driver for three-phase brushless DC motors assembled in a PowerSO36 package (L6230PD), with overcurrent and thermal protection. The L6230 driver is optimized for six-step and FOC algorithms thanks to independent current sensing.
