* Retro Pwm Pcb Board
Tiny and powerful!
Boards can be used with up to 4s as it's P-Fet buffered and 40amp max, RPP on the Vin (to protect the timer).
You can use either a 10K or a 100K pot with these depending if you like the buzz from the mosfet switching on/off frequency.
The potentiometer can be mounted straight onto the board to take up even less space making it very compact package
Pwm pulses the voltage making it hard for voltmeters to read correctly voltmeter should be used for battery level
