ESP12E on a stick

After having played with the WEMOS D1 mini I needed to switch to the bare-bone ESP12E device so that I can get a feel for it and integrate it into a custom PCB design. This is not easy, as the ESP12E pinning is not compatible with a breadboard. This is the solution I came up with:
esp12estick1

esp12estick2

esp12estick3
