This listing is for completed board as shown in the photo. It uses IC micro controller to operating with a built-in soft-start to prevent electric shock. In addition, voltage control and mosfet driver circuits are provided to increase working efficiency low to high frequency ranges plus resistant to noisy signal.

Technical information:
- Motor speed : Using IC micro controller PWM (Pulse With Modulation) for motor speed control.
- Built-in soft start for protecting electric shock when supply the voltage.
- There is the limit voltage circuit at the gate of mosfet for protecting the over voltage and noisy signal.
- Using the mosfet driver circuit to greatly increase working efficiency of the circuit in ranges of frequency as follows
         @ 100Hz, 200Hz, 400Hz, 800Hz, 1.6kHz, 3.2kHz, 6.4kHz and 12.8kHz

- Power supply : 8-30VDC. (select by jumper and motor).
- Load voltage : 8-30VDC./ 30A. max.
- PWM duty cycle : adjustable from 0% to 100%.
- PCB dimensions : 3.83 x 1.57 in.
- The schematic and diagram how to connect.
