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 also upgraded the R4 WiFi's analog-to-digital converter (ADC), which is responsible for reading data from the analog inputs. On the Rev3, the ADC supports up to 10-bit resolution, with ...

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.

The Uno R4 maintains backward compatibility with shields from previous versions, thanks to its 5V operating voltage and standard Uno pinout. It introduces new power circuitry, enabling it to be ...

Keeping the pinout, voltage and form factor unchanged from the UNO R3 ensures maximum hardware and electrical compatibility with existing shields and projects while allowing the UNO R4 boards to be a ...
