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.

Received good product Product is very easy to use Specially good product for home automation Use with 16 relay module
This product is awesome for beginners in coding. They can have fun and learn plenty of coding tricks with it.
Got components in time with perfectly wrapped condition
I got this along with and Arduino UNO clone. This is really good value for money if you want the ESP 8266 functionality as well.
Received with good condition
This product quality was awesome. Don waste time with other website
Nice
VERY GOOD COMPATIBLE WITH ARDUINO BOARD
I got this product very fact and it is working very good
Very good build quality
