#Ignore this ESP8266 board by @davedarko

It has been a while since I got the boards and at the time I left some thoughts on the project page. I really like its simplicity which made assembly very easy. To develop on such a board I'd prefer an onboard serial converter just to eliminate having to chain several gadgets together but I have some use cases for the boards nonetheless:

I've added 2mm headers to the ESP-12E footprint such that I can just plug in an ESP-12E or an ESP-01. I use this board to test new ESP modules to make sure they work after their month-long trip.

I haven't implemented the second use case yet but I plan on making the other one into a wireless serial bridge using the ESP-Link firmware and a virtual serial port tunnel to make it compatible with just about every program/tool out there. The reason for this is that I do most work on my laptop when it's actually on my lap and this way I won't have to worry about the USB cable pulling the devboard and breadboard off my desk.

And finally here are some mods that I made for/to the board:

Simple adapter board to connect power rails. This was more feasible than using those female headers with long pins and plugging it into the top.

I used angled headers for the serial header and the Vusb/Vin pin. The idea was to make it possible to plug it directly into the serial converter (or some in-between adapter board) and have them not be perpendicular to each other. Also added some rubber feet for good measure.

When I read your comments on the project of @jaromir.sukuba I had totally forgotten about that! Glad to see those pictures again! I like the rubber feet. Thanks again for sharing.

Haha, well it's a good thing he convinced me to make this project then ;)

The last three pictures are new btw. I also used those rubber feet on the acrylic case of #Pro Trinket USB Keyboard; if you get some, make sure they are taller than anything protruding from the surface (pin headers, tact switches for this board or screws in case of the acrylic case), mine are just borderline working.
