![]() ![]() The Arm Cortex-M4 core includes a Floating Point Unit (FPU), which enhances performance for certain applications that require floating-point calculations. To handle more complex projects, the UNO R4 is equipped with 32 kB of SRAM and 256 kB of flash memory. This allows the UNO R4 boards to serve as high-performance drop-in replacements. The UNO R4 maintains the standard form factor, shield compatibility, and 5V power supply of the popular UNO R3, ensuring maximum hardware and electrical compatibility with existing shields and projects. The RA4M1 microcontroller is based on the Arm Cortex-M4 core and operates at a clock speed of 48 MHz, enabling higher processing power. The UNO R4 is powered by a 32-bit microcontroller, the RA4M1 processor from Renesas, which provides up to 16 times the clock speed, memory, and flash storage compared to the previous 8-bit technology. The new UNO R4 is powered by a 32-bit microcontroller and is available in two versions: the minimalist UNO R4 Minima and the feature-rich UNO R4 WiFi, satisfying the financial and artistic demands of the maker community. The release of the next-generation UNO board by Arduino represents a considerable upgrade to its 8-bit technology. ![]()
