Arduino ABX00080 Board Uno Rev4 Minima

The Arduino UNO R4 boards feature a powerful 32-bit microcontroller that provides more computing power and memory, while maintaining the standard UNO form factor and 5 V operating voltage. As such, it is an excellent option for beginners and experienced electronics enthusiasts who want to expand the limits of their projects.

While the well-known characteristics of the UN family are maintained, the UNO R4 boards offer a 32-bit architecture and exciting new features for
Manufacturer.

The Arduino UNO R4 boards are equipped with a powerful 32-bit microcontroller from Renesas, which provides more computing power, memory and on-board peripherals. It is important that these improvements do not affect compatibility with existing shields and accessories, nor do they require changes to the standard form factor or the 5 V operating voltage. With its rugged design and reliable performance, the UNO R4 is a valuable addition to the Arduino ecosystem. It is suitable for beginners as well as for experienced electronics enthusiasts, who want to extend the limits of their projects.

Backwards compatible hardware
The UNO R4 has the same pin assignment and 5V operating voltage as its predecessor, the Arduino UNO R3. This means that existing shields and projects can easily be ported to the new board.

New on-board peripherals
The UNO R4 has several exciting new peripherals, including a 12-bit DAC, CAN BUS, OP AMP and SWD port. These additions extend the opportunities for developers and enable more advanced projects.

More memory and faster speed
With more memory (16x) and faster clock speed (3x), the UNO R4 minima can perform more precise calculations and process more complex projects. This allows developers to create even more sophisticated and advanced projects.

HID VIA USB-C
The UNO R4 can simulate a mouse or keyboard when connected to the USB-C connector. With this feature, makers can create fast and cool interfaces with minimal effort.

Higher voltage range and electrical robustness
The UNO R4 boards can be operated with up to 24 V, also thanks to an improved theme design. The circuit is equipped with several protective devices to reduce the risk of wiring faults by inexperienced users damaging the circuit board or the PC. In addition, the RA4M1 micro-controller has an overcurrent protection on the pins, which offers additional protection against errors.

Support for capacitive touch
The RA4M1 microcontroller, used on the UNO R4 boards, supports capacitive touch from the house.

Powerful and affordable
The UNO R4 minima offers impressive performance at a competitive price. This board is a particularly affordable option that underlines Arduino's commitment to making high-end technology accessible to everyone.

SWD pins for debugging
The integrated SWD-port offers a simple and reliable possibility for connecting debugging buttons of other manufacturers. This feature ensures that projects are more reliable and enables efficient troubleshooting of potential problems.
