Arduino UNO R4 Minima

The improved and expanded Arduino UNO R4 Minima is equipped with a powerful 32-bit microcontroller from Renesas. Look forward to increased processor performance, expanded memory, and a whole new level of on-board peripherals. Compatibility with existing shields and accessories is maintained, and no change to the standard form factor or 5V operating voltage is necessary. The UNO R4 Minima, a trusted new addition to the Arduino ecosystem, is suitable for both beginners and experienced electronics enthusiasts. Whether you're just starting out or looking to push the boundaries of your projects, this robust board delivers reliable performance for every use.


What the new UNO R4 Minima offers:

  • Hardware compatibility with the UNO form factor: The UNO R4 Minima retains the same form factor, pinout, and 5V operating voltage as its predecessor, UNO R3. This ensures a seamless transition for existing shields and projects by leveraging the extensive and unique pre-existing ecosystem for Arduino UNO.
  • Improved memory and higher clock rate: Get ready for more accurate computations and the ability to master complex projects with aplomb. The UNO R4 Minima comes with more memory and a faster CPU clock rate, allowing you to effortlessly handle demanding tasks.
  • Additional on-board peripherals: The UNO R4 Minima introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP. These additional components provide enhanced capabilities and flexibility in your designs.
  • Extended 24V tolerance: The UNO R4 Minima now supports a wider input voltage range, allowing for power supply voltages of up to 24V. This enables seamless integration with motors, LED strips, and other actuators, simplifying your projects by utilizing a single power source.
  • SWD connector: Debugging is a critical aspect of every project. Simply connect an external debugger to the UNO R4 Minima and
  • HID support: The UNO R4 Minima comes with integrated HID (Human Interface Device) support, allowing it to simulate a mouse or keyboard when connected to a computer via a USB cable. This handy feature facilitates sending keystrokes and mouse movements to a computer, thus enhancing usability and functionality.
