Description:
 
Full integration on one board: U n o R3 ATmega 328 and WiFi ESP8266 with memory 32Mb (MegaByte). All of the modules can work together or each separately. And everyone has their own pinout headers.
The convenient solution for the development of new projects requiring U n o and WiFi.
Via USB you can update sketches and firmvare for ATmega328 and for ESP8266. For this on board have the USB-serial converter CH340G.
Use this board is very simple.
The board has DIP-switch, to connect the modules.
For example, to: USB and ATmega328, USB and ESP8266, ATmega328 and ESP8266.
