Mega WiFi Dev. Board (Mega2560 + ESP8266 + CH340G + Micro USB)

It is a customized version of the classic ARDUINO MEGA R3 board. Full integration of Atmel ATmega2560 microcontroller and ESP8266 Wi-Fi IC, with 32 Mb (megabits) of flash memory, and CH340G USB-TTL converter on a single board. All components can be set up to work together or independently.All of the modules can work together or separately. And everyone has their own pinout headers. The convenient solution for the development of new projects requiring Uno and WiFi. Via USB you can update sketches and firmware for ATmega328 and for ESP8266.

For this onboard have the USB-serial converter CH340G.The board has DIP-switch to connect the modules. For example, to USB and ATmeg2560, USB and ESP8266, ATmega2560 and ESP8266.The operating mode is selected by means of DIP switches on-board.

Switch status and model selection:

Also, have the switch to change of connecting port between ATmega2560 and ESP8266. After choosing the mode of the board, can proceed to set up the IDE. It is important that when the ESP8266 module is programming, it is necessary to press the button “Mode”.
