We have also selected Arduino Uno R4 WiFi for our IoT & Edge AI Project Challenge as one of three boards you can choose from. Check out the contest page for more information and don’t miss the chance ...

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.
