Arduino, the world's leading open-source hardware and software platform, today announced the launch of its next-generation UNO board, a significant re ...

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.

The first step I took in building this was to build a 3D model in Rhino. I based it on the Arduino Uno dimensions, and then started creating the parts based upon my real-world materials and scale.

The Arduino Uno R4 is to have a Renesas RA4M1 32-bit Arm Cortex-M4 microcontroller, and there are “no plans to discontinue the popular Uno R3” , according to Arduino, which estimates that R4 will ...

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.

Arduino collaborated closely with partners Renesas and Espressif to create the ‘most compatible and powerful maker board on the market’.

Arduino, the open-source hardware and software platform, has launched its next-generation UNO board, a significant revision of its 8-bit technology.

Arduino Uno R4 WiFi comes with built-in Wi-Fi and Bluetooth capabilities, along with additional pins and a new, faster processor.

The Arduino team explain more about the origins of the iconic Arduino UNO microcontroller “As familiar as we all are with the UNO, there’s probably a lot you don’t know about the iconic ...
