Arduino UNO R4 WiFi development board.
The Arduino UNO R4 WiFi is a powerful 32-bit development board with built-in Wi-Fi, Bluetooth LE, LED matrix, and full UNO shield compatibility.
The Arduino UNO R4 WiFi Development Board is the next-generation upgrade to the classic UNO series, combining enhanced performance with built-in wireless connectivity. It is powered by the Renesas RA4M1 32-bit ARM Cortex-M4 microcontroller, delivering higher processing power, more memory, and improved efficiency compared to previous UNO boards.
This board features integrated Wi-Fi® and Bluetooth® Low Energy through the ESP32-S3 module, enabling seamless IoT, smart automation, and wireless communication projects. With 14 digital I/O pins, 6 analog inputs, 6 PWM outputs, and 5V operating logic, it remains fully compatible with existing Arduino UNO shields and accessories.
Additional highlights include a 12×8 LED matrix for visual output, a DAC (Digital-to-Analog Converter) for audio and waveform generation, CAN bus support, and enhanced power management. Programmable via the Arduino IDE, the UNO R4 WiFi is ideal for advanced robotics, IoT systems, wireless control, and embedded development projects.
