A lot of people have used ESP8266 to add inexpensive WiFi connectivity to their projects, but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266.

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE.

This innovative project features a custom PCB that contains all the relevant connections required to program an ATMega328 (including external oscillator), ATTiny, ESP8266, Arduino mini pro ...
