Arduino UNO R4 Minima – Unlocking More Power in a Familiar Form
Take your ideas to the next level with the Arduino UNO R4 Minima Board — a 32-bit upgrade with unbeatable performance! Featuring the Renesas RA4M1 microcontroller at 48MHz, it brings faster computing, advanced math functions via its Floating Point Unit (FPU), and a larger memory footprint compared to previous UNO boards.
With 256KB Flash, 32KB SRAM, and 8KB EEPROM, you can develop complex, memory-intensive applications with ease. The board's integrated 14-bit ADC and 12-bit DAC deliver unmatched analog signal precision, making it ideal for high-resolution sensor readings and analog output.
A built-in Real-Time Clock (RTC) and Memory Protection Unit (MPU) ensure that your applications are not only accurate but also secure. Best of all, the 5V operating voltage means you can reuse most of your existing UNO-compatible shields without any hardware modifications.
