GET NOTIFIED WHEN IN STOCK SUBSCRIBE TO THE WAITING LISTSECONDARYThe Arduino UNO R4 will come in two versions – UNO R4 WiFi and UNO R4 Minima – offering unprecedented performance and possibilities for the maker community.
Portenta C33
The UNO R4 is powered by the Renesas RA4M1 32-bit Cortex®-M4 processor, providing a significant boost in processing power, memory, and functionality.
The WiFi version comes with an Espressif S3 WiFi module in addition to the RA4M1, expanding creative opportunities for makers, educators, and hobbyists alike; while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features.

Opta Lite
Designed for maximum compatibility, the UNO R4 maintains the same form factor, shield compatibility, and 5V operating voltage as its predecessor.
Software compatibility is also a priority, with most existing libraries and examples working seamlessly on the new board.
Portenta C33
The Arduino UNO R4, featuring the Renesas RA4M1 (Arm Cortex®-M4) running at 48MHz, boasts a 3x performance increase over the UNO R3.
Additionally, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.
Responding to community feedback, the USB port is now USB-C, and the maximum power supply voltage has been raised to 24V with an enhanced thermal design.
The board includes a CAN bus and an SPI port, enabling users to reduce wiring and perform parallel tasks by connecting multiple shields.
A 12-bit analog DAC is also provided on the new board.
