CH340G Board compatible with Arduino
The Uno+WiFi R3 is a fully integrated board that combines the Uno R3 ATmega 328 microcontroller with the WiFi ESP8266 chip, along with 8Mb of memory, all on a single board. Both modules can operate together or separately, each with their own pinout headers.
This board provides a convenient solution for developing new projects that require both Uno and WiFi functionalities. It includes a USB-serial converter, CH340G, allowing for easy updating of sketches and firmware for both ATmega328 and Node MCU ESP8266.
Essentially a modernized version of the classic Arduino UNO R3 board, the Uno+WiFi R3 offers simple operations and includes a DIP switch to connect the different modules in various configurations. LED lights are provided for connecting peripheral sensors and modules, making it a versatile choice for a wide range of projects.
