Hi everybody,

I soldered the pins in a new WeMos D1 R3 mini and I tried to check with the voltometer if everything works fine. Here is what I 've found:

- 5V pin gives around 4,68V which I don't know if it is ok. Any suggestions are highly welcomed.
- 3,3V pins gives 3,29 which is almost perfect I think (the voltometer might be inserting a minor error)
- Pins D0, D5, D6, D7, D8 from one side of the board work as expected (when set to high 3,27-3.29V and when left without setting they have some voltage around 0,02-0,20 - I think it's ok).
- On the other side of the WeMos the party begins:

I started with D4 and this seemed to work fine. I set it to high, measured 3,28, I left it without setting and measured 0,08. I then moved to D3 and set it to high measuring 3,29V. I immediately changed the code to D2 and tried to set this high and normally I measured 3,29V but then I remembered I didn't check with out setting the D3 pin and removed the jumper wire from D2 and plugged it...
