How it work:

Code: Select allPC <---(USB)---> ft232 <---(via jumper)---> Atmege328

               ESP8266 Module

Atmega328 <---(Uart) --> ESP8266 Module

Any advise about this board?

- Wed Apr 01, 2015 5:47 am #13173 Leave the ATmega out. Use a port extender for the ESP8266 instead.
I use AD5593RBRUZ.
Having two chips on the board, that both have to be programmed and have to communicate with each other will overwhelm beginners.
Using just the ESP (with the Arduino IDE) and having a port extender, that is supported transparently by the wiring lib, will be much easier.

- Wed Apr 01, 2015 6:15 am #13175 you don't really need to program both when you want to make something.

- Wed Apr 01, 2015 6:20 am #13176 Why then use an ESP-12 instead of an ESP-01?
