Features

• Hardware Compatibility with UNO Form Factor: The UNO R4 WiFi maintains the same form factor, pinout, and $5\text{V}$ operating voltage as its predecessor, the UNO R3, ensuring a seamless transition for existing shields and projects.

• Extended Memory and Faster Clock: The UNO R4 WiFi has more memory and a faster clock speed, allowing for more precise calculations and effortlessly executing complex projects.

• Extra On-Board Peripherals: The UNO R4 WiFi introduces a range of on-board peripherals, including a $12\text{-bit}$ DAC, CAN BUS, and OP AMP, offering expanded capabilities and design flexibility.

• Extended $24\text{V}$ Tolerance: The UNO R4 WiFi supports a wider input voltage range, enabling seamless integration with motors, LED strips, and other actuators that use a single power source.

• HID Support: With built-in HID support, the UNO R4 WiFi can simulate a mouse or keyboard when connected to a computer via USB, making it easy to send keystrokes and mouse movements.

• Wi-Fi® and Bluetooth®: The UNO R4 WiFi includes an ESP32-S3 module, allowing makers to add wireless connectivity to their projects. Combined with the Arduino IoT Cloud, makers can monitor and control their projects remotely.

• Qwiic Connection: The UNO R4 WiFi features a Qwiic I2C connector, allowing for easy connection to nodes from the extensive Qwiic ecosystem. Adapter cables also enable compatibility with sensors and actuators based on other connectors.

• Support for Battery-Powered RTC: The UNO R4 WiFi has extra pins, including an “OFF” pin to turn off the board and a “VRTC” pin to keep the internal Real-Time Clock powered and running.

• LED Matrix: The UNO R4 WiFi has a bright $12\text{x}8$ red LED matrix, ideal for creative projects with animations or plotting sensor data, eliminating the need for extra hardware.

• Runtime Error Diagnostics: The UNO R4 WiFi includes a debugging mechanism that detects runtime crashes and provides detailed explanations and hints about the line of code causing the crash.

With all these features packed into the familiar UNO form factor, this is the perfect time to upgrade your project or start your maker journey. The UNO R4 WiFi offers unmatched versatility and possibilities for makers of all levels.
