Arduino UNO R4 is a giant leap forward for an open source community of millions
Here at Arduino we are thrilled to announce a new, revolutionary revision of the iconic UNO board, which will expand the concept of the open-source brand’s most iconic and popular product while providing the maker community with a long-awaited update on performance and possibilities.
The Arduino UNO R4 indeed preserves the well-known features of the UNO family – standard form factor, shield compatibility, 5V operating voltage, outstanding robustness – while offering no less than a 32-bit Cortex®-M4 and a 3-to-16x increase in clock speed, memory and flash storage.
This huge leap forward starts with a new processor by Renesas, a global leader in microcontrollers, analog, power and SoC products. While over 10 million users have enjoyed playing and working with Arduino UNO R3’s 8-bit microcontroller for more than a decade, the new RA4-series MCU will open up endless new project opportunities for more advanced makers, and bring the board up to speed with current standards.
