The Uno+WiFi R3 combines the Uno R3 ATmega328 and WiFi ESP8266 with 8MB memory, offering full integration on a single board. Both modules can operate together or independently, each with its own pinout headers.
This board provides a convenient solution for developing projects that require both Uno and WiFi functionalities. You can easily update sketches and firmware for both ATmega328 and ESP8266 via USB, thanks to the onboard USB-serial converter CH340G.
A modernized version of the classic Arduino UNO R3, this board seamlessly integrates the ATmega328 microcontroller and the ESP8266 Wi-Fi chip with 8MB memory. Each microcontroller is equipped with LEDs for connecting peripheral sensors and modules.
Operating the board is straightforward, featuring a DIP switch that toggle interaction modes between the ATmega328 and ESP8266. The board also includes a DIP switch to connect various modules, such as USB and ATmega328, USB and ESP8266, or ATmega328 and ESP8266.
