TESTED AND WORKING
(Support will only be offered on projects marked “TESTED AND WORKING”, and only on the moxbods facebook group.
Any previous projects that are now deleted are used at your own risk.)
This is a PWM board with Reverse Polarity Protection, courtesy of a P-channel Mosfet.
This is NOT a buffered circuit, so recommended max input voltage is 12.6V (3S), but I have tested it up to 14V and although it worked, it may severely limit the life of the device. Only use higher than 12.6V at your own risk.
Recommended potentiometer value: 10K - 50K
Parts list:
1 x 0603 1K resistor
1 x 0603 0.1uF capacitor
1 x 0603 0.01uF capacitor
1 x SOT23 p-channel mosfet
1 x BAT54S dual diode (SOT23 package)
1 x SOIC-8 555 timer IC
1 x 3-pin through hole potentiometer, 10K to 50K recommended
