About this item

The Arduino UNO R4 Minima is an advanced evolution of the classic UNO platform, designed to offer greater performance and memory for more demanding projects. Powered by a Renesas RA4M1 32-bit microcontroller, the board provides significant improvements over its predecessors, including 256 kB of flash memory, 32 kB of SRAM, and 8 kB of data memory (EEPROM). Despite these upgrades, the UNO R4 Minima maintains the familiar 5V operating voltage, ensuring compatibility with most existing UNO shields and accessories. However, due to the microcontroller architecture change, software compatibility may vary, and some libraries may require updates.Compact and powerful, the UNO R4 Minima is ideal for users who need more resources for complex tasks such as real-time data processing, multitasking, or advanced peripheral interfacing. The board features a standard UNO form factor but omits the USB-to-serial converter and debugger found on the R4 WiFi version, making it a lightweight and cost-effective option for embedded systems, industrial automation, and rapid prototyping.Whether you’re upgrading from an older UNO or starting a high-performance project, the UNO R4 Minima delivers cutting-edge capabilities in a familiar, accessible package.
