Pin descriptions are available on the underside of the board, which may not be convenient e.g. on a contact plate.
The board is thin enough that it was enough to solder the goldpin from the other side and there would be no problem - such a PROtip for those in need. Fact, then we cover "RESET" but I have never used it too much anyway. In addition, you can always attach your microswitch to the pin.
