UNO R4 Minima Development Module

UNO R4 Minima Development Module

The UNO R4 Minima Development Module is a microcontroller board that combines the classic Arduino UNO form factor with the powerful 32-bit Renesas RA4M1 microcontroller; it is enhanced with additional G-V-S pin groups to simplify sensor and servo connections.

At the heart of the board lies the Renesas R7FA4M1AB3CFM, which features a 32-bit Arm Cortex-M4 architecture and operates at a clock frequency of 48 MHz.

Thanks to its 256KB Flash, 32KB SRAM, and 8KB EEPROM capacity, it offers higher processing and memory capabilities compared to classic UNO R3 boards based on the ATmega328P.
