Overview

Arduino UNO R4 prototyping boards preserve the standard form factor, shield compatibility, 5V power supply and robustness of the UNO range while featuring the Renesas RA4M1 32-bit microcontroller with 48MHz Arm® Cortex®-M4 and a 16-fold increase in memory. Thanks to enhanced thermal design, the UNO R4 boards can be powered up to 24V. You can choose between the lightweight UNO R4 Minima or the full-fledged UNO R4 WiFi depending on your skill level, general budget and project.
