Description
Discover the power of wireless connectivity and extensive capabilities with the Arduino UNO R4 WiFi development board. This board combines the processing power of the Renesas RA4M1 microcontroller with the wireless connectivity of Espressif’s ESP32-S3 module. Whether you’re an experienced maker or just starting out on your first project, the UNO R4 WiFi provides everything you need to ignite your creativity.
While retaining the familiar UNO form factor and 5V supply voltage, the UNO R4 WiFi development board provides a seamless transition for existing shields and projects. Thanks to its expanded memory capacity and faster clock speed, this new version is capable of performing more precise calculations and driving complex projects with ease.
What really sets this development board apart is the additional on-board functionality. With a 12-bit DAC, CAN BUS, and OP AMP, the UNO R4 WiFi development board offers extensive capabilities and flexibility when designing your projects. In addition, the UNO R4 WiFi supports a wider input voltage range from 6V to 24V, allowing for seamless integration with motors, LED strips, and other actuators with just a single power source.
With built-in HID support, the UNO R4 WiFi development board can simulate a mouse or keyboard when connected to a computer via USB. This allows you to easily send keystrokes and mouse movements from your project.
With the ESP32-S3 module onboard, the UNO R4 WiFi development board offers Wi-Fi and Bluetooth connectivity. You can add wireless capabilities to your projects and monitor and control them remotely using the Arduino IoT Cloud.
The Qwiic connector on the UNO R4 WiFi development board makes it possible to easily connect to devices from the extensive Qwiic ecosystem via I2C. With adapter cables, it is also possible to use sensors and actuators with other connectors.
Thanks to the support for battery-powered RTC (Real-Time Clock), the UNO R4 WiFi development board can keep the internal clock running even when the power is off. This keeps the timekeeping and keeps you up to date.
The bright 12x8 LED matrix on the UNO R4 WiFi development board allows you to realize creative projects with animations or displaying sensor data without the need for additional hardware.
With the integrated debugging mechanism on the UNO R4 WiFi development board, you can detect runtime errors and get detailed explanations and hints about the code that caused the crash. This makes it easier to track down and solve problems in your project.
With the Arduino UNO R4 WiFi development board, now is the perfect time to upgrade your project or start your maker journey. This board offers unparalleled versatility and capability for makers of all levels.
