Please can I have some help with a boost/buck convertor? Answered
I want to use one of the cheap boost/buck convertor to increase and decrease variably my 12v power supply. I have now purchase and (bricked) 4 now as each time I remove the board bound pots and solder in ones I can mount on the front panel I must wire them incorrectly even though I mirror the pin set up. I have tried all types of pots single turn and multi-turn always make sure I match the resistance value of the original.
Please help, what is this rooky doing wrong?
