Hi guys,
I got a Nano32 board from rudi;) and try to use it with Arduino IDE 1.6.12; Win10
Followed the instructions http://microcontrollerkits.blogspot.de/2016/10/esp32-develop-with-arduino-ide.html
Fixed the first problem "no module named serial" http://www.ayarafun.com/2016/10/arduino-esp32-first ...
