This Arduino Mega R3 +WiFi ATmega2560+ESP8266 Module CH340G defined as a modernized version programmable board compatible with Arduino Mega board. This module with fully integrated microcontroller ATmega2560 and a Wi-Fi chip ESP8266 with 32 MB memory on one board. All modules in this board can either work together or individually. And everyone has their own pinout headers.
This module is an ideal solution for developing new projects that require Uno and WiFi. We can update sketches and firmware for ATmega2560 and for ESP8266 Via USB. The onboard CH340G functions as the USB-serial converter. It is a modernized version of the classic Arduino Mega R3 board. This fully integrated ATmega2560 and WiFi ESP8266 features 8Mb (MegaByte) memory. The DIP switch present on the board switches the modes of interaction of microcontrollers. Hence each of the microcontrollers has led to connecting peripheral sensors and modules.
This board is quite simple to operate and install. The board has DIP-switch, to connect the modules. For example, to USB and ATmega2560, USB and ESP8266, ATmega2560 and ESP8266. The CH340 board based on ESP8266 designed as an integrated chip specifically to fulfill the needs of a new connected world. It consists of all-in-one microcontroller + WiFi platforms widely used with WiFi for IoT applications.
The Arduino Mega board designed as an open-source microcontroller board based on the Microchip ATmega2560 microcontroller and developed by Arduino. cc. The board consists of sets of 54 digital and 16 analog input/output pins. Thus can be interfaced to various expansion boards and other circuits. Moreover, this Arduino Uno compatible board operates at a supply voltage of 5V at a current of 800mA.
