Arduino Mega + WiFi R3 Board – ATmega2560 + ESP8266 (32Mb) with CH340G USB-TTL

Arduino Mega + WiFi R3 Board – ATmega2560 + ESP8266 (32Mb) with CH340G USB-TTL

This dual-core development board combines the power of the Arduino Mega 2560 (ATmega2560) and the ESP8266 WiFi module (32Mb) into one fully integrated solution. Ideal for projects that require both rich I/O capability and wireless connectivity.

Key Features

Fully Integrated Board
Includes both the ATmega2560 (Arduino Mega) and ESP8266 WiFi SoC, with independent pin headers and shared communication interfaces.

32Mb ESP8266 Flash
Comes with a high-capacity 32Mb flash memory on the ESP8266 for advanced WiFi projects, OTA updates, or storing large firmware and data logs.

CH340G USB-TTL Converter
Onboard CH340G chip allows easy programming of both the ATmega2560 and ESP8266 through a single USB connection. Fully compatible with Arduino IDE.

Modular Switching via DIP-Switch
Easily toggle communication paths between:

• USB and ATmega2560

• USB and ESP8266

• ATmega2560 and ESP8266

Flexible Operation
Use ATmega2560 and ESP8266 independently or together. Ideal for projects that require local processing with Arduino and cloud connectivity via WiFi.

Use Case Examples

• Smart IoT Gateways: Collect data with ATmega2560 and upload via ESP8266 to cloud platforms like ThingSpeak or Blynk.

• Home Automation: Run local sensors/actuators on Arduino and control them remotely via WiFi.

• OTA-Enabled Devices: Store large sketches and update firmware over-the-air using ESP8266.

• Complex Robotics: Use the Mega’s abundant GPIOs for motor/sensor control and stream telemetry over WiFi.
