Digital Input

The G-3V3-S connector: 3V3 stands for 3.3 V power voltage, G is for GND (ground), S is for signal. GVS is a
standard sensor connector, which enables you to plug onto servos and various sensors.
7.3 Motor Input
Two motor input connectors in total: M1+, M1- and M2+, M2- separately control a channel of a DC motor.
