The Arduino Nano R4 pairs the Renesas RA4M1 microcontroller with a Nano form factor, featuring USB-C, Qwiic connector, CAN support, RTC, DAC, OpAmp, and HID capabilities.


Nano R4 merges Arduino’s signature ease of use with the powerful Renesas RA4M1 microcontroller, enabling effortless scaling from prototyping on the UNO R4 to production-ready applications.

Compact and versatile, the Nano R4 maintains the same pinout as other boards in the Nano family and features castellated pins for easy hardware integration, an on-board Qwiic connector for rapid sensor and peripheral expansion, and a programmable RGB LED for intuitive system feedback. Its single-sided component design makes it ideal for space-constrained products and SMD soldering on custom carrier boards, ensuring a seamless transition from lab testing to real-world deployment.

Thanks to its compatibility with familiar Arduino tools and libraries (including those for the Arduino UNO R4 Minima), the Nano R4 offers developers and designers a streamlined path to build compact, connected solutions.

Available with loose, unsoldered headers, or with headers pre-soldered - please select an option before adding to cart.
