    Pinout

    • Power Selection Jumper: The motors can be powered by external power supply(PWMIN) or VIN from Arduino control board(e.g., UNO). Default is VIN showed by the diagram. Note: There are two jumpers in parallel that can afford heavy current.

    • PWMIN Terminal: Used to connect to external power.

    • Motor Terminal: Used to connect motors by screw terminals(M1- M1+ M2- M2+) or PIN headers(1 2 3 4).

    • Analog 3Pin Port: Used to connect sensors or actuators. Note: pinout is (+ - S).

    • Motor Indicator: The red LED lights if Mn+ is positive, whereas the green LED lights.

    • Control Port: Used to control speed and direction of motor. You can get port's description in the "Control Table" printed on the shield.

    • Control Function Table:

    Name Function
    En Mn Speed control(PWM)
    Mn Mn Direction Control
    • Control Signal Truth Table:
    En Mn State
    L X Disable Mn
    H L Mn Foreward(Mn+ is positive)
    H H Mn Backward(Mn+ is negative)

    Note: n of "Mn" or "En" is 1, 2
