Hardware compatibility in UNO form factor: The UNO R4 Minima maintains the same form factor, pinout, and 5V operating voltage as its predecessor, the UNO R3. This ensures a seamless transition for existing shields and projects and leverages the already established and unique ecosystem of the Arduino UNO.

Extended storage capacity and faster clocking: Get ready for more precise calculations and effortless handling of complex projects. The UNO R4 Minima features increased memory and faster clocks that enable you to tackle demanding tasks with ease.

Additional onboard peripherals: The UNO R4 Minima introduces a range of onboard peripherals including a 12-bit DAC, CAN BUS and OP AMP. These additional components increase your capabilities and flexibility in your designs.

Extended 24V Tolerance: The UNO R4 Minima now supports a wider input voltage range and allows power sources up to 24V. This facilitates seamless integration with motors, LED strips and other actuators and simplifies your projects by using a single power source.

SWD connection: Debugging is a critical aspect of any project. Simply connect an external debugger to the UNO R4 Minima and monitor the inner workings of your system effortlessly. Stay in control and gain valuable insights.

HID support: The UNO R4 Minima comes with built-in HID (Human Interface Device) support and allows it to simulate a mouse or keyboard when connected to a computer via a USB cable. This handy feature allows keystrokes and mouse movements to be sent to a computer, improving usability and functionality.
