The Uno WiFi R3 ATmega328P+NodeMCU ESP8266 board combines the functionalities of the Uno R3 ATmega328 and the ESP8266 Wi-Fi module, all on a single board with 8MB of memory. This allows for seamless integration between the microcontroller and Wi-Fi, making it ideal for projects that require both. Each component, the ATmega328 and ESP8266, has its own set of pin headers, enabling them to function either together or independently.
This board is a great solution for developing new projects that involve Wi-Fi connectivity. It comes equipped with a CH340G USB-to-TTL serial converter, enabling you to easily upload sketches and firmware to both the ATmega328 and the ESP8266 via USB.
This is a modernized version of the classic Arduino UNO R3, featuring full integration of the ATmega328 microcontroller and the ESP8266 Wi-Fi chip with 8MB of memory. Each microcontroller has dedicated connections for peripheral sensors and modules. The DIP switch on the board allows you to easily toggle between the ATmega328 and the ESP8266, depending on your project requirements.
The board also has a DIP switch for selecting interaction modes between the ATmega328 and ESP8266. You can configure it to connect the USB to either the ATmega328 or the ESP8266, or even between the two microcontrollers themselves, allowing for versatile operations.
