Arduino UNO R4 Minima
The Arduino UNO R4 Minima is a compact and powerful microcontroller board designed for makers, students, and engineers seeking enhanced performance in a familiar form factor. Powered by a 32-bit Renesas RA4M1 microcontroller featuring a 48 MHz Arm® Cortex®-M4 core with 256 KB of flash and 32 KB of RAM, the UNO R4 Minima offers significantly more processing power and memory compared to its predecessors. It maintains the classic UNO layout for compatibility with existing shields and accessories while introducing modern capabilities such as expanded I/O, a built-in DAC, and enhanced analog features. Ideal for embedded projects and prototyping, the UNO R4 Minima delivers next-generation performance with Arduino's trademark simplicity and reliability.
- 32-bit development board, previously based on 8-bit AVR
- Standard 14 digital I/O ports, 6 analog channels, and dedicated pins for I²C, SPI, and UART connections
- Larger memory: 8 times more flash memory (256 kB) and 16 times more SRAM (32 kB)
- Easy power management: Barrel jack connector supports input voltages from 6-24 V, eliminating the need for additional circuitry
