The Uno R4 Minima is a more cost-effective version without these features. **Q: Is the Arduino Uno R4 series backward compatible with my old projects?** A: Yes, the Uno R4 boards maintain the same form factor, pinout, and 5V operating voltage as the UNO R3, ensuring compatibility with your existing shields and projects. **Q: What is the Qwiic connector for?** A: The Uno R4 WiFi's Qwiic connector allows for quick plug-and-play integration with a vast ecosystem of I2C sensors and modules, including our own Arduino Modulinos. **Q: How does the Uno R4 compare to the original Uno R3?** A: The Uno R4 is a significant upgrade with a faster 32-bit processor, more memory, and new features like a DAC and CAN Bus, while keeping the classic 5V operating voltage. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Arduino R4 wifi *by D***V on 1 March 2025* Good ### ⭐⭐ Review *by B***D on 18 March 2024* De arduino is beschadigd aangekomen ### ⭐⭐⭐⭐⭐ Review *by K***E on 20 July 2025* Der Arduino ist wie gewohnt ein tolles Board für kleine Projekte. Die neue Generation mit Arm Cortex M0 ermöglicht nochmals deutlich mehr Projekt im Vergleich zum 1. Version. Der Preis dafür ist akzeptabel. Einziger Kritikpunkt bisher: ich hatte Probleme den USB-Port dem Board in der IDE zuzuordnen bzw. die Verbindung wieder zu löschen. Es gibt dafür Workflows im Internet, die allerdings recht unhandlich sind.
