## Questions & Answers

**Q: What is the main difference between the Uno R4 WiFi and the Uno R4 Minima?**
A: The Uno R4 WiFi includes an on-board ESP32-S3 for Wi-Fi and Bluetooth, plus an LED matrix. 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.
