UNO R4 Minima Board ( Generic )

Product Description

The Arduino UNO R4 Minima represents the next generation of the classic UNO platform, now powered by a high-performance 32-bit microcontroller. At its core is the Renesas RA4M1 (R7FA4M1AB3CFM), featuring a 48 MHz Arm® Cortex®-M4 processor for improved speed, efficiency, and reliability across a wide range of applications. With expanded memory compared to earlier UNO models, the R4 Minima offers 256 kB Flash, 32 kB SRAM, and 8 kB EEPROM, giving developers more room for advanced code and data storage.

Operating at 5V DC, the UNO R4 Minima maintains hardware compatibility with the traditional UNO form factor, allowing you to safely use most existing 5V shields and accessories. While hardware compatibility is retained, software adjustments may be required due to the updated microcontroller architecture.

Compact, powerful, and reliable, the UNO R4 Minima is an excellent choice for embedded systems, prototyping, automation, and electronics development projects.
