Arduino Mega WiFi R3 (ATmega2560 + ESP8266)
Arduino Mega WiFi R3 (ATmega2560 + ESP8266)
Full integration on one board: Arduino Mega R3 ATmega2560 and WiFi ESP8266 with memory. All of the modules can work together or each separately. And everyone has their own pinout headers.
The convenient solution for the Arduino development of new projects requiring Arduino Uno and WiFi.
Via USB you can update sketches and firmware for ATmega2560 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 ATmeg2560 USB and ESP8266 ATmega2560 and ESP8266.
