Description

The Arduino UNO R3 with Integrated WiFi Module is a variant of the classic Arduino UNO board, featuring built-in Wi-Fi connectivity. This combination makes it ideal for Internet of Things (IoT) projects, where you can control and monitor devices over the internet or a local network. The integrated Wi-Fi module typically used with these boards is the ESP8266 or ESP32, both of which are low-cost, powerful Wi-Fi modules. <h3>Key Features of the Arduino UNO R3 with Integrated Wi-Fi
