The "Mega WiFi R3 Atmega2560 NodeMCU ESP8266 32Mb Memory USB-TTL CH340G" is a development board that combines two microcontrollers: the ATmega2560 and the ESP8266, similar to the previous examples mentioned.

Here's a breakdown of the key components and features of this development board:

ATmega2560: The ATmega2560 is a microcontroller chip that is commonly used in Arduino Mega boards. It is based on the AVR architecture, runs at 16 MHz, and has 256 KB of flash memory, 8 KB of SRAM, and 4 KB of EEPROM. It's compatible with the Arduino IDE and is often used for projects that require a lot of I/O pins and processing power.

ESP8266: The ESP8266 is a popular WiFi module with its own microcontroller. It is known for its low cost, low power consumption, and built-in WiFi capabilities. It's often used for IoT projects and can be programmed using the Arduino IDE or other development environments that support the ESP8266.

32MB Memory: This board comes equipped with 32MB of flash memory, providing ample space for storing firmware, data, and other resources.

USB-TTL CH340G: The CH340G is a USB-to-UART converter chip. It allows you to connect the board to your computer via USB for programming and serial communication. You may need to install drivers for the CH340G on your computer if they are not already installed.

Compatibility: The board is designed to be compatible with the Arduino Mega R3 form factor, making it compatible with Arduino Mega shields and libraries. This makes it easy for those familiar with Arduino to work with this development board.

NodeMCU Form Factor: Similar to the previous example, this board also follows the NodeMCU form factor, which includes a micro USB port for power and programming and GPIO pins for connecting external devices.

Programming: You can program both the ATmega2560 and the ESP8266 using the Arduino IDE or other supported development environments. This allows you to take advantage of the extensive Arduino ecosystem for the ATmega2560 and the WiFi capabilities of the ESP8266.

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

Switch status and model selection:

Connection↓/Switch No.→ 1 2 3 4 5 6 7 8
CH340 connects to ESP8266 (upload sketch) OFF OFF OFF OFF ON ON ON NoUSE
CH340 connect to ESP8266 (connect) OFF OFF OFF OFF ON ON OFF NoUSE
CH340 connects to ATmega2560 (upload sketch) OFF OFF ON ON OFF OFF OFF NoUSE
CH340 connect to Mega2560 COM3 connect to ESP8266 ON ON ON ON OFF OFF OFF NoUSE
CH340 connects to ESP8266 (upload sketch) OFF OFF OFF OFF OFF OFF OFF NoUSE

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”
