Arduino introduced the latest addition to its UNO family: the UNO R4. With no plans to discontinue the popular UNO R3, the UNO R4 will come in two versions: UNO R4 WiFi and UNO R4 Minima — offering unprecedented performance and possibilities for the maker community.
The UNO R4 is powered by the Renesas RA4M1 32-bit microcontroller based on the Arm Cortex-M4 core, providing a significant boost in processing power, memory, and functionality. The Wi-Fi version comes with an Espressif S3 WiFi module, expanding creative opportunities for makers, educators, and hobbyists alike.
