ESP12S double-sided plug-in module

Introduction:

This module is intended to be used as a general purpose module.
This module is to weld ESP12S to a small board for double-sided direct plug installation. The purpose is to use ESP12S in some projects where the PCB size is very tight (such as smart WIFI sockets). Because the PCB in these projects usually does not have enough tile space, it can only be installed directly.
All IO ports of ESP12S (except IO15 port) have been lead out. Because IO15 port needs to be at low level all the time, it cannot be lead out for use.
You can also directly use ESP12F instead of ESP12S. The pins of ESP12F are backward compatible with ESP12S.
