esp-12 esp-07 (esp8266) programming board and breadboard adapter
When I went to use esp12 and esp07, and the first problem was how to put it on the breadboard, luckily I found an adapter developed by tweeto, and that was what I needed, but I would like to make it easier to use, so I redesigned it smaller and added some labels to identify the pins, than I create a PCB to use It as programming board.
