esp8266 module types

I’ve been looking at the different ESP8266 modules that are available and have collected those I found here for reference. They seem to differ in terms of which pins are broken out, if a ceramic antenna, or PCB antenna is used, or if they have a connector for an external antenna. There seem to be quite a few options available…

In addition to these, Olimex also have two custom modules. For which they’ve also kindly provided eagle files: find them here, pics below.
