Arduino UNO R4 Minima Development Board

The Arduino UNO R4 Minima brings 32-bit processing power to the classic UNO form factor. Powered by a Renesas RA4M1 Cortex-M4 microcontroller running at 48MHz, it is an ideal choice for students, makers, and educators looking to upgrade their prototyping capabilities.

Renesas RA4M1 Cortex-M4 processor

The board features a 32-bit Renesas RA4M1 Arm Cortex-M4 core operating at a clock speed of 48MHz. This delivers significantly faster processing and improved performance over traditional 8-bit boards.

Expanded 256KB flash memory

With 256KB of onboard flash memory, the board provides ample space for complex sketches and larger libraries. This extra capacity allows you to build more sophisticated embedded projects without memory bottlenecks.

Integrated CAN bus support

A built-in Controller Area Network (CAN) bus interface enables reliable communication with automotive systems and industrial networks. It allows direct connection to multiple nodes without requiring external expansion shields.

Modern USB-C connector

Power and programming are handled via a modern USB-C connection for improved convenience and durability. It simplifies connectivity with current PCs and laptops.

Precision 12-bit DAC output

An integrated 12-bit digital-to-analogue converter allows the board to produce genuine analogue voltage outputs. This is ideal for precision audio, waveform generation, and sensitive instrument control.

Standard 5V UNO compatibility

The board maintains the standard UNO pinout and operates natively at 5V logic. This ensures seamless compatibility with existing shields, sensors, and 5V peripherals.
