-Both ADC1 and ADC2 connector have two RC-servo like pinouts. There are ground, supply and input-output pins. It is easy to connect simple sensors like potentiometer, thermistor, IR distance sensor and ultrasonic distance sensor to these pins. IO pins can be used as +5 V compatible inputs or outputs with +3,3 V high level. These connectors can also be used to control RC-servos with software PWM when the servo accepts 3,3 V signal.+Both ADC1 and ADC2 connectors have two RC-servo like pinouts.

-COMM connector is a combination of UART, SPI and I2C interfaces. Beside +5 V supply it contains +3,3 V supply which supplies up to 700 mA. COMM connector is intended to connect with ARM-CAN User Interface and that is why it also features 2 ADC and 1 PWM pins, which are used by the joystick and speaker. +COMM connector is a combination of UART, SPI and I2C interfaces.
