The enhanced and improved Arduino UNO R4 Minima is equipped with a powerful 32-bit microcontroller from Renesas. Get ready for increased computing power, expanded memory and a whole new level of on-board peripherals.
Compatibility with existing shields and accessories is maintained and there is no need to make any changes to the standard form factor or 5V operating voltage.
As a member of the Arduino ecosystem, the UNO R4 Minima is a reliable addition for both beginners and experienced electronics enthusiasts.
Whether you're just starting out or looking to push the boundaries of your existing projects, this robust board delivers reliable performance every time.
Backward hardware compatibility
The UNO R4 retains the same pinout and 5 V operating voltage as its predecessor, the Arduino UNO R3. This means that existing shields and projects can be easily ported to the new board.
New on-board peripherals
The UNO R4 Minima has several exciting new peripherals, including a 12-bit DAC, CAN BUS, OP AMP and SWD port. These additions expand the possibilities for developers and enable more advanced projects.
More memory and faster clock speeds
Prepare for more precise calculations, as well as the ability to tackle complex projects with ease. The UNO R4 Minima has more memory and a higher clock speed, so you can tackle the most demanding tasks with ease.
HID via USB-C
The UNO R4 can simulate a mouse or keyboard when connected to its USB-C port. This feature allows makers to create fast and cool interfaces with minimal effort.
Wider voltage range and power handling
The UNO R4 boards can operate at up to 24 V, thanks in part to an improved design. The circuit is equipped with several protections to reduce the likelihood that wiring errors by inexperienced users can damage the board or PC. In addition, the RA4M1 microcontroller has overcurrent protection on the pins, which provides additional protection against errors.
Capacitive touch support
The RA4M1 microcontroller used on the UNO R4 boards natively supports capacitive touch.
