Hi, I'm very new here ,i have trouble for connecting this board. Maybe some one can help me out on this.
* Where do i connect battery power?
* Where do i connect output motor?
* Where do i connect electronic throttle? (with permanent magnet)
* Where do i connect the power switch?

Hope some one can figure this out.
Thanx in advance

Looks suspiciously like a DIY board someone put together using one of the Chinese PCB Manuf. for the bare board.

Blue wire is supply +ve (common to board and motor so use heavy duty wire).
White wire goes to motor +ve (heavy duty wire needed)
Black wire goes to motor -ve and supply -ve (heavy duty wires again)

The speed controller (potentiometer) though.......... anyone?

Thanx ,
Well throttle,i need power supply and a signal wire i guess. So green it will be... there are 2 greens, so i guess 1 will be throttle signal and the other for power switch?

It seems as though the speed signal (PWM?) will be an external signal as all that is on the board is a quad comparator IC and a couple of power IC's.

Whole shebang probably not worth the effort given the low cost of complete pwm dc motor controllers on the internet.
