I just bought this 4 Channel DC Motor Driver (FD04A Flexibot Driver).
I have some question about it.
Is it the 2x7 IDE is connected to microcontroller (supplied by 5v)?
If the rated voltage of the motor is 12v, mean we have to power this circuit with 12v?
Mean relay to trip the 12v circuit is built in this board?
If i want to build the driver circuit myself with L293 or L298, how to i control the speed ?
Program the microcontroller?
Thank.
