Arduino introduces its new module »Uno R4«. It is the successor of the R3 module and contains a Wi-Fi module in the extended version. It is also the first Arduino module with 32-bit microcontroller.

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.

Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V.

We must cover the new Arduino devboard recently released, the Uno WiFi Rev 2, with integrated Wi-Fi connectivity in an IoT-friendly form.

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

The UNO R4 WiFi features Wi-Fi and Bluetooth Low Energy connectivity, while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features.

Now for the minutiae: there’s an Arduino Uno with built-in Wi-Fi that receives UDP commands from a phone to raise and lower the clock at the appropriate times.

The official Arduino development team has this week announced that it is now possible to program the UNO Wifi Rev2, that comes with the Arduino CTC Go!

See all 100 here. Arduino and Atmel have collaborated to create a secure version of Arduino's Wi-Fi Shield 101 and it looks like a great tool for both hackers and commercial developers interested in ...
