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.

Announced a few months ago, the Arduino UNO R4 Minima and the Arduino UNO R4 WiFi have now been released officially. So, now that they really exist, let’s have a closer look at them. The Renesas ...

The Arduino UNO R4 Minima and the Arduino UNO R4 WiFi. But apart from the obvious wireless connectivity hinted by the name what other differences do the microcontrollers have.

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, ...

The Arduino UNO R4 will be available in two versions, the ‘WiFi’ with an ESP32-S3 module, and the ‘Minima’. The R4 feels more like an update of the Arduino Zero, which, with its 32-bit ARM Cortex-M0 ...

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 ...

The Arduino UNO R3 is a development board based on the 8-bit ATMega328P microcontroller. It is one of the most iconic boards ever designed, and it is known and loved by millions of makers worldwide.

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.

Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...
