I am developing on ESP8266 with ESP-12E on a full fledged development board (Like: https://www.amazon.de/gp/product/B0182JOWOK/) with USB and pin out for all I/O. Works like a champ.
Now, how do I move my software and my circuit (OLED, buttons and such) on a ‘production board’? (Like: https://www.amazon.de/gp/product/B00U293Y5M/)
The small board only has 8 pins. Is there a description available how to flash and wire those? Maybe even a small board?
