Product Description (Detailed):

The Arduino UNO R4 WiFi combines the simplicity of the classic UNO with advanced features to supercharge your IoT and embedded projects. Powered by a 32-bit RA4M1 Cortex-M4 MCU and an ESP32-S3 coprocessor, it offers blazing-fast performance, onboard Wi-Fi + Bluetooth connectivity, and real-time monitoring capabilities via the Arduino IDE and Arduino Cloud.

Designed with the same form factor as the UNO R3, it maintains full shield compatibility while adding new power: higher clock speed, more RAM, larger flash, CAN bus support, and real-time serial plotting. The onboard Qwiic/I²C connector, DAC, and HID capabilities make it ideal for modern applications in automation, robotics, machine learning, and remote sensing.
