Arduino UNO R4 Minima

The Arduino UNO R4 boards feature a powerful 32-bit microcontroller that offers more processing power and memory while maintaining the standard UNO form factor and 5V operating voltage. As such, they are an excellent option for both beginners and experienced electronics enthusiasts looking to push the boundaries of their projects. While the familiar characteristics of the UNO family are preserved, the UNO R4 boards provide a 32-bit architecture and exciting new features for makers.

The Arduino UNO R4 boards are equipped with a powerful 32-bit microcontroller from Renesas, which offers more processing power, memory, and on-board peripherals. Importantly, these enhancements do not compromise compatibility with existing shields and accessories, nor do they require changes to the standard form factor or the 5V operating voltage. Thanks to their robust design and reliable performance, the UNO R4 is a valuable addition to the Arduino ecosystem. It is suitable for both beginners and experienced electronics enthusiasts who want to expand the limits of their projects.

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

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