Your IoT project shouldn't need a breadboard full of extra modules just to get Wi-Fi working. The Arduino UNO R4 WiFi bakes it all in — Renesas RA4M1 for the heavy lifting, ESP32-S3 handling Wi-Fi and Bluetooth on board. You get a 12×8 LED matrix for instant visual feedback, a Qwiic connector so sensor wiring stays clean, and enough processing headroom to stop guessing. One board. One USB cable.
