What is the main difference between the Uno R4 WiFi and the Uno R4 Minima?

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.

Is the Arduino Uno R4 series backward compatible with my old projects?

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.

What is the Qwiic connector for?

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.

How does the Uno R4 compare to the original Uno R3?

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.
