UNO WiFi R3 ATmega328P ESP8266 32Mb

The UNO WiFi R3 is a highly integrated development board that combines the familiar Arduino UNO R3 form factor with the powerful connectivity of the ESP8266 Wi-Fi chip on a single board. This versatile board features two CPUs: an 8-bit ATmega328P microcontroller and a 32-bit ESP8266, allowing for both independent and collaborative operation. It is an ideal solution for developing new projects that require both traditional microcontroller functionality and Wi-Fi connectivity for the Internet of Things (IoT). The board includes a Micro-USB connection for easy programming of both chips via the CH340G USB-TTL converter.
