I see great potential in this board. Small, fast, has lots of memory (compared to arduino), integrated wifi and display, runs directly from a LiPo battery and relatively cheap, too. The USB socket isn't it strongest point due to mechanical (design) problems of the board but it's at least stable on mine. In my opinion it would be better on the backside of the PCB and have solder pins for the battery instead. Here is a quick start for beginners: http://www.instructables.com/id/Programming-the-WeMos-Using-Arduino-SoftwareIDE/ Description, code example: http://simplestuffmatters.com/?p=69 Library for the OLED: https://github.com/olikraus/u8g2

Tried it already, working as described. The OLED is good looking. Very nice soldering quality. Can recommend buying just for the size. Soon to be used to display authentication codes.

Nice microcontroller. USB is flimsy so you must be careful when inserting the plug in or it will get loose.
