The Arduino UNO R4 WiFi combines the power of the Renesas RA4M1 microcontroller with the wireless capabilities of the ESP32-S3 from Espressif. Packed with exciting new peripherals, including a 12x8 LED matrix, Qwiic connector, VRTC, and OFF pin, this board is a versatile choice for makers of all levels. Whether you're adding wireless connectivity to an existing project or starting a new one, the UNO R4 WiFi has everything you need to spark your creativity.

Features:

• Hardware Compatibility with UNO Form Factor: Just like its predecessor, the UNO R4 WiFi maintains the UNO form factor, pinout, and 5 V operating voltage. This ensures a seamless transition for existing shields and projects.
• Expanded Memory and Faster Clock: The UNO R4 WiFi boasts increased memory and a faster clock speed, allowing for precise calculations and effortless handling of complex projects.
• Extra On-Board Peripherals: It introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP, offering expanded capabilities and design flexibility.
• Extended 24 V Tolerance: With support for a wider input voltage range, the UNO R4 WiFi seamlessly integrates with motors, LED strips, and other actuators using a single power source.
• HID Support: Featuring built-in HID support, the UNO R4 WiFi can simulate a mouse or keyboard when connected to a computer via USB-C, making it easy to send keystrokes and mouse movements.
• Wi-Fi® and Bluetooth®: Equipped with an ESP32-S3 module, this board enables makers to add wireless connectivity to their projects. With the Arduino IoT Cloud, you can monitor and control your projects remotely.
• Qwiic Connector: The UNO R4 WiFi includes a Qwiic I2C connector, simplifying connections to nodes from the extensive Qwiic ecosystem. Adapter cables also ensure compatibility with sensors and actuators based on other connectors.
• Support for Battery-Powered RTC: Additional pins, including an "OFF" pin to turn off the board and a "VRTC" pin to keep the internal Real-Time Clock powered, provide enhanced functionality.
• LED Matrix: Featuring a bright 12x8 red LED matrix, this board is ideal for creative projects with animations or plotting sensor data, eliminating the need for additional hardware.
• Diagnostics for Runtime Errors: The UNO R4 WiFi includes an error-catching mechanism that detects runtime crashes, providing detailed explanations and hints about the code line causing the crash.
