On-board 3.3V LDO output, maximum current 10mA. The SimpleFOCMini DC brushless motor driver board uses the DRV8313 chip. The DRV8313 provides three independently controllable half-H-bridge driver, mainly used to drive brushless DC motor. Only the control signal and the motor UVW three-phase line need to be connect to control the motor rotations. The SPWM and SPVMW control algorithms are supported, but the traditional 6-step commutation control algorithm is not.
