7.2
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.
7.4
Motor Control
P8 and P12 (internally connected pins) relatively control the rotating direction of the motors connected on M1
or M2.
P1 and P2 control the motor speed (internally connected pins).
Pin Function
Note
P8
Direction control of
M1
Positive rotation under active high-voltage level; negative rotation under active
low-voltage level.
P1
Speed control of M1
PWM
P2
Speed control of M2
PWM
P12
Direction control of
M2
Positive rotation under active high-voltage level; negative rotation under active
low-voltage level.
An active high-voltage level means an active high signal (3 V or 5 V), and digital 1 in software (firmware).
An active low-voltage level means an active low signal (0 V ground), and digital 0 in software (firmware).
