Quoted from _litz:There's apparently a trim pot providing +/- 500mv of adjustment, so it should be possible to trim it above 5.00v.
This sounds like it makes a perfect replacement for WPC driver boards so that you don't have to add the 11 ohm or 22 ohm resistor to get it to output 5.1 or 5.2 volts instead of the 4.9V that they usually output with the stock configuration.
