STM32F4 32Bit ARM microcontroller.
5V 1.5A output for external electronics from the buck converter integrated on the DRV8302.
For single ESC current: Up to 150A for a couple of seconds or about 50A continuous depending on the temperature and air circulation around the PCB.
Wireless WII nunchuk (Nyko Kama) control through the I2C port. This is convenient for electric skateboards.
Adaptive PWM frequency to get as good ADC measurements as possible.
