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, and production-ready solutions.
