Arduino Nano R4

The Arduino Nano R4 is a compact and powerful microcontroller board that combines the proven form factor of the Nano series with modern 32-bit technology. The package includes two 15-pin header strips that are not pre-installed. This makes the board perfect for users who want to decide whether to solder it directly, plug it into a socket strip, or integrate it into a project without headers. It is powered by the Renesas RA4M1 (ARM Cortex-M4F, 48 MHz), which offers significantly more computing power, an expanded range of functions, and improved peripherals compared to older Nano models. With 256 kB flash memory, 32 kB RAM, a 12-bit DAC, and high-resolution ADCs, the board is ideal for precise measurement and control tasks. The integrated Qwiic/Stemma-QT interface allows easy connection of a variety of sensors, displays, and modules without complex wiring. The USB-C port is used for both programming and power supply, alternatively, an external supply between 6 V and 21 V can be used via the Vin pin. Thanks to full compatibility with the Arduino IDE and the Arduino Cloud, getting started is just as easy as developing complex applications. In addition to classic C/C++ programming, countless libraries and example projects can be integrated, making it easy to implement complex systems quickly. The board is suitable for hobbyists and professional applications, as well as for use in schools and universities to teach practical electronics and programming skills.
