Description Introducing the Arduino UNO R4 Minima! This board boasts the RA4M1 microprocessor from Renesas, delivering increased processing power, expanded memory, and additional peripherals. And the best part? It stays true to the reliable UNO form factor and operates at a practical 5 V voltage. Brace yourself for an upgrade like no other with the Arduino UNO R4 Minima! A WiFi version, Arduino UNO R4 Wifi, is also available if you need an added WiFi capability. For new projects, we no longer recommend the Arduino Uno R3 unless you need to use libraries that can only work with the ATmega328 microcontroller. If you need to use an ATmega328 with an Arduino footprint, we sell a compatible version of the Uno R3. Overview Enhanced and improved, the Arduino UNO R4 Minima is armed with a powerful 32-bitmicrocontroller courtesy of Renesas. Brace yourself for increased processing power,expanded memory, and a whole new level of onboard peripherals. The best part?Compatibility with existing shields and accessories remains intact, and there's no need to make any changes to the standard form factor or 5 V operating voltage. Joining the Arduino ecosystem, the UNO R4 Minima is a trusty addition suitable for both beginners and seasoned electronics enthusiasts. Whether you're just starting out or looking to push the boundaries of your projects, this robust board delivers reliable performance every time. Here's what the UNO R4 Minima brings to the table: Hardware compatibility with UNO form factor: The UNO R4 Minima maintains the same form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3.
