About this item

The Arduino® UNO R4 Minima is the first board in the UNO family to feature a 32-bit microcontroller, delivering a significant performance upgrade while maintaining the familiar UNO form factor. It is powered by the Renesas RA4M1 series microcontroller (R7FA4M1AB3CFM#AA0), equipped with a 48 MHz Arm® Cortex®-M4 CPU.This board offers expanded memory compared to its predecessors, including:256 kB Flash memory32 kB SRAM8 kB EEPROMOperating at 5 V, the UNO R4 Minima ensures compatibility with most UNO-form-factor shields that adhere to the same voltage level. However, due to the shift to a different microcontroller architecture, some shields may require software modifications to function correctly.Ideal for users looking to transition from 8-bit to 32-bit development without losing UNO compatibility, the UNO R4 Minima provides enhanced performance, more memory, and a future-ready platform for embedded projects.
