#18710 Red is power and blue is transmission I think
This is almost the same as ESP12 board( which has no power red LED) It has an antenna outlet and have a look in the Wiki right at the top of this page .there are pics and maybe a circuit diagram but if not and you find one could you post it there please

This guy has a parts library for the versions so it may give you hints
