Arduino® UNO R4 Minima

The Arduino UNO R4 Minima combines the classic, well-loved approach and compatibility of the UNO series with dramatically increased processing power, more memory and modern 32-bit capabilities. At its heart is the powerful Renesas RA4M1 microcontroller (Arm Cortex-M4 at 48 MHz), making it an excellent basis for educational projects, automation and advanced robotics applications.

Key Features & Upgrades
Classic Form Factor & Compatibility: Retains the familiar dimensions, pinout and 5 V operating voltage, allowing most existing shields to be used.

Modern USB-C Connectivity: Easy and reliable connection for programming and power.

Increased Memory: Features 256 KB Flash, 32 KB SRAM and 8 KB EEPROM for more demanding programs.

Advanced Built-in Functions: Includes a 12-bit DAC, Real-Time Clock (RTC), USB HID support (operation as a keyboard/keyboard), CAN Bus, SWD connectivity for debugging and a built-in Operational Amplifier (OP AMP).

VIN Supply Range (6–24 V): Makes it easy to connect directly to motors, LED strips and other actuators.
