Have you had your hands on an Arduino Uno R4 since its release? Let us know in the comments. Many electronics engineers and makers have spent countless hours with the Arduino Uno R3 and Arduino Nano, so we're curious to hear your feedback on the Uno R4. By the way, if you missed the dedicated live episode of Elektor Engineering Insights #24 when it aired last year, check out the summarized version below.
In this interview with Alessandro Ranellucci of Arduino, we cover all the key highlights from the original recording. The video condenses the most important technical updates and features of the Arduino Uno R4, offering a quick yet comprehensive look at what makes this new board stand out. Whether you're interested in the shift to a 32-bit microcontroller or the Wi-Fi variant, this recap provides all the essential information to get you up to speed. Alessandro explains how this new microcontroller ensures backward compatibility with the Arduino ecosystem and brings new features like built-in DAC for direct analog output, CAN bus, and more.
Alessandro also addresses the durability of the Uno R4, with protection diodes to prevent damage from common user mistakes. The new features, such as the switch to a USB-C connector and the option to have built-in Wi-Fi are of course discussed. On the Wi-Fi variant of the Uno R4, the integration of the ESP32 co-processor also adds Bluetooth capabilities. For visual feedback, it features a multiplexed 96-LED matrix. Arduino provides a library for easy control, and a web tool to create custom animations, allowing for quick and creative user feedback and light effects. Many other topics are covered, not forgetting a few tips to better understand compiler error messages, as well as debugging possibilities.
