有了UNO R4 WiFi,您可以輕鬆升級您的項目,並添加無線連接,擴展當前設置的範圍。如果這是您的第一個項目,這個板子擁有您激發創意所需的一切。

  • Hardware compatibility with UNO form factor: The UNO R4 WiFi maintains the same form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3, ensuring 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, enabling more precise calculations and effortless handling of complex projects.
  • Extra on-board peripherals: The UNO R4 WiFi introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP, providing expanded capabilities and design flexibility.
  • Extended 24 V tolerance: The UNO R4 WiFi supports a wider input voltage range, allowing seamless integration with motors, LED strips, and other actuators using 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 hosts an ESP32-S3 module, enabling makers to add wireless connectivity to their projects. Combined with the Arduino IoT Cloud, makers can monitor and control their projects remotely.
  • Qwiic connector: The UNO R4 WiFi features a Qwiic I2C connector, allowing 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 includes additional 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 incorporates a bright 12x8 red LED matrix, 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 and provides detailed explanations and hints about the code line causing the crash.
With all these features packed into the well-known UNO form factor, now is the perfect time to upgrade your project or embark on your maker journey. The UNO R4 WiFi offers unparalleled versatility and possibilities for makers of all levels.





Can I use hardware compatible with the Arduino UNO R3 with the Arduino UNO R4 WiFi?

Yes, the Arduino UNO R4 WiFi was specifically designed to ensure compatibility with previous shields and compatible hardware developed for the Arduino UNO R3. The UNO R4 WiFi maintains the same mechanical and electrical compatibility, allowing you to seamlessly use your existing shields and hardware with the new board. This makes it easy to upgrade to the UNO R4 WiFi without the need for significant changes or adaptations to your projects.

Can I use hardware compatible with the Arduino UNO WiFi Rev2 with the Arduino UNO R4 WiFi?
Yes, the Arduino UNO R4 WiFi is fully compatible with previous shields and hardware developed for the UNO WiFi Rev2. Both boards share the same UNO form factor and 5 V operating voltage. However, it's important to note that depending on the design, there may be changes in the pinout elements. Please refer to the documentation and pinout diagrams for specific details and compatibility considerations.

Can I use my sketch developed for the UNO R3 in the UNO R4?
Yes, if your sketch was developed using the Arduino API. In case you are using instructions only available for the AVR architecture, some changes need to be made to ensure compatibility.

Are all libraries compatible with the UNO R3 also compatible with the UNO R4 WiFi?
No, some UNO R3 libraries use instructions of the AVR architecture that are not compatible with the architecture of the UNO R4 WiFi, however there are libraries that have already been ported as part of our early adopters program or are based on the Arduino API.

What is the on-board LED Matrix on the Arduino UNO R4 WiFi and how can I use it? 
The on-board LED Matrix is a fully addressable 12x8 (96 points) red matrix that utilizes Charlieplexing to individually control each point. To get started, simply download the “Arduino UNO R4 boards” core. This will grant you access to the user-friendly Arduino_LED_Matrix API, allowing you to program and control the LED Matrix. More information can be found here.

Are there any tools available to assist with creating animations for the LED Matrix?
Absolutely! We have developed a graphic tool specifically designed to help makers create and export their own animations. This way, you can unleash your creativity and make the most of this exciting feature. Find more information on the Arduino Labs website.
