The two Motors (Motor A and B ) can be controlled via two inputs:
- Direction (DA / DB): high or low for the direction
- Enable (PA / PB): used to control motor speed over an PWM signal
There is also an notSleep (!SL) input. If this pin is unconnected or low the ICs goes into a sleep-state. It must be pulled up to operate Motors.
Supply Voltage can be 7V or lower (min. 2V).
For more Information take a look at the data sheet!
Note to DRV8835
This board is also usable for DRV8835. This driver IC has a split supply for logic and moor but no sleep function. So the pin labeld with sleep (!SL) will be the logic supply pin (Vcc) and Vcc is the motor supply (Vm).
