Nano R4 merges Arduinoās 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.

Is my sketch for the Arduino UNO R4 Minima compatible with the Arduino Nano R4?
Yes, your sketch for the UNO R4 Minima is compatible with the Nano R4. However, you will need to adjust the sketch to align with the Nano R4's pinout.
Can I use hardware compatible with the Arduino Nano (A000005) with the Arduino Nano R4?
Yes, the Arduino Nano R4 was specifically designed to ensure compatibility with previous shields and compatible hardware developed for the Arduino Nano. The Nano R4 maintains the same pinout and electrical compatibility, allowing you to seamlessly use your existing shields and hardware with the new board. This makes it easy to upgrade to the Nano R4 without the need for significant changes or adaptations to your projects.
Can I use my sketch developed for the Arduino Nano (A000005) in the Nano R4?
Yes, if your sketch was developed using the Arduino API. In case you are using instructions only available for the AVR architecture, some changes need to be made to ensure compatibility.
