LED Pads on the 3PDT Charge Pump Board

[benny_profane]

Since project boards have the indicator LED tied to VCC and a switched ground for bypass, the LED will vary in intensity if using the charge pump board's 9v/18v switched output. It'd be useful to have dedicated LED pads that use a static 9v supply on the board itself for bypass indication. This brings it inline with the power supply and indicator switching used on boards with integrated charge pumps.

That's not a bad idea. I'll have to see if I can squeeze it in there somehow...

That'd mean we'd also need to add a current limiting resistor to the board as well.

Yep. There's definitely space, though. On a related note, is there a build doc/schematic available? It's rather straightforward, but I wanted to double check stuff for some extended use cases.

The schematic is a bit rough, but here you go.
