Arduino UNO R4 WiFi Board

The Next-Generation Arduino UNO is Here

Unleash the full potential of your creative projects with the Arduino UNO R4 WiFi. This powerful board combines the robust processing of the Renesas RA4M1 microcontroller with the seamless wireless connectivity of the Espressif ESP32-S3. It's the perfect upgrade for seasoned makers and the ultimate starting point for beginners.

The UNO R4 WiFi maintains the classic UNO form factor, pinout, and 5V operating voltage, ensuring full compatibility with your existing shields and projects. Transitioning your setup has never been easier.

Key Features:

• Integrated Wi-Fi® and Bluetooth®: The onboard ESP32-S3 module lets you effortlessly connect your projects to the internet or other devices. Monitor and control your creations remotely with the Arduino IoT Cloud.
• Onboard 12x8 LED Matrix: Bring your projects to life! Create animations, display sensor data, or craft unique visual interfaces directly on the board without any additional hardware.
• Expanded Memory & Faster Clock: With more memory and a 48 MHz clock speed, the UNO R4 WiFi handles complex calculations and demanding projects with ease.
• Rich Onboard Peripherals: Go beyond the basics with a built-in 12-bit DAC, CAN BUS, and an operational amplifier (OP AMP), opening up new possibilities for advanced applications.
• Qwiic Connectivity: The integrated Qwiic I2C connector provides plug-and-play access to an extensive ecosystem of sensors, actuators, and accessories.
• HID Support: Emulate a mouse or keyboard when connected via USB. Effortlessly send keystrokes and mouse movements to a computer, perfect for custom input devices.
• Extended Voltage Range: Power your projects more flexibly. The UNO R4 WiFi supports an input voltage range of 6-24V, allowing you to drive motors, LED strips, and other actuators with a single power source.
• Real-Time Clock (RTC): Includes a VRTC pin to keep the internal RTC powered with a separate battery, ensuring accurate timekeeping even when the main power is off.
