Uno R4 WiFi compatible is a powerful clone of the original Arduino Uno R4 WiFi and is not manufactured by the official Arduino brand. This board combines the processing power of Renesas' RA4M1 microcontroller with the wireless connectivity of Espressif's ESP32-S3. Additionally, the Uno R4 WiFi comes equipped with an onboard 12x8 LED matrix, Qwiic connector, HID support, VRTC, and an OFF pin, covering all potential makers' needs for their next project.

• Expanded memory and faster clock speed with additional onboard peripherals:This board features expanded memory and a faster clock speed, allowing you to calculate more precisely and tackle complex projects with ease. New onboard peripherals include a 12-bit DAC, CAN BUS, and an operational amplifier, increasing capabilities and design flexibility.
• Hardware Compatibility and Wider Input Voltage Range:The board retains hardware compatibility with the Uno form factor, operating at 5V. It now supports a wider input voltage range, up to 24V, allowing for seamless integration with motors, LED strips, and other actuators. This makes it easy to port projects developed with previous Uno form factor boards.
  
• Wi-Fi/Bluetooth and Arduino Cloud Compatibility:With a built-in ESP32-S3 coprocessor, it offers seamless Wi-Fi and Bluetooth connectivity. This board is fully compatible with Arduino Cloud, enabling remote data storage, interactive dashboards, and Over-the-Air uploads.
  
• LED matrix creativity:The Uno R4 WiFi features a vibrant 12x8 red LED matrix, ideal for creative projects and animating visuals without any additional hardware.
