Arduino empowers makers’ creativity and passion for innovation with a robust new board that’s perfect for all users, from beginners to experts – allowing anyone to easily connect to the internet and create IoT projects.
The UNO universe expands with UNO R4 WiFi: the same industry-standard form factor at 5V operating voltage, but with the enhanced performance of a RA4M1 32-bit microcontroller by Renesas with ESP32-S3-MINI coprocessor – for increased computational power, memory and speed – as well as Wi-Fi® and Bluetooth® connectivity, a 12 x 8 LED matrix, and a Qwiic connector.
After 20 years, Arduino is still providing its community with the tools to change the world and explore new horizons.
Your user-friendly, accessible UNO just took a quantum leap forward: Arduino UNO R4 is a 32-bit microprocessor offering more speed, memory, connectors and connectivity options than any version of the board before. Out of this world, and into the future.
UNO R4 preserves the standard form factor, shield compatibility, 5V power supply and robustness of the UNO range while offering no less than a 32-bit Cortex® M4 and a 15-fold increase in memory. The best prototyping and learning tool for anyone just got better.
Choose between the lightweight UNO R4 Minima and the full-fledged UNO R4 WiFi depending on your skill level, general budget and the project you have in mind. Both include limitless ease of use and the support of our stellar community.
Arduino UNO R4 WiFi offers connectivity options that open the door to IoT, welcoming you to a world of enhanced capabilities and features. It has everything you find in the Minima variant, plus:
– Wi-Fi® / Bluetooth® Low Energy
– Fully-addressable LED matrix with 96 LEDs – Qwiic I2C connector
– RTC (with support for a buffer battery)
