I've recently bought one of these pwm boards for testing , they've got a much wider frequency and duty cycle than I've tried on previous projects.
I'd like to actually mount the board to try out its practicality, I'd buy more as they're cheaper than I can make myself bizzarIey. Problem is I need to replace the pots with smd tactile switched digi pots, freq up/down and duty up/down.
I believe they're 2M ohm and 10k ohm. I've found numerous 10k digi pots and a few related schematics, can't find a 2M digi pot nor any schematic.
Anyone know how to swap out the pots on this, maybe have a schematic you can share?
Cheers Mick.
