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.

Operating mode is selected by means of DIP switches on-board:

Switch status and mode selection:

It is important that when the ESP8266 module is programming, it is necessary to press the button “Mode”
