Will try that too tomorrow, right now I made a photo with the 2 resistors that I though ware used as a volt divider ...
That appears to be s a 224 (220k) and a 010 (1 Ohm) in series. There is indeed a via connecting to the 010 - wonder where that is leading to. The other end of the 010 is apparently linked to the top plane of the board, most likely GND or Vcc (3.3V).
That doesn't really make sense, as the values are so far apart that you get nearly 0V or Vcc (depending on what that plane is connected to) on that via at all times. So I wonder what I'm missing there.
