Note:

. x in INAx, INBx, PWMx, Mx_A, Mx_B is the channel number, 1 or 2.

. H for high level, L for low level, X is irrelevant to level, Z is high-impedance state.

. Don't switch the motor direction if it is still in high speed, adjust the speed to 0% gradually by PWM before switching, otherwise, the

driver may be damaged.

. Note: it is in High level when the signal input pin is floating.

Tutorial

The tutorial presents how to control motor driver board by Arduino UNO and drive two motors simultaneously.
