Arduino NANO R4 with Renesas RA4M, USB-C and Qwiic

Compact and versatile, the Nano R4 maintains the same pinout as other boards in the Nano family and features castellated holes for easy hardware integration, an integrated Qwiic connector for rapid expansion of sensors and peripherals, and a programmable RGB LED for intuitive system feedback.

Its single-sided component design makes it ideal for products with space constraints and for SMD soldering onto custom carrier boards, ensuring a rapid transition from lab tests to real-world implementation.

Thanks to its compatibility with the most well-known Arduino tools and libraries (including those for Arduino UNO R4 Minima), the Nano R4 offers developers and designers a simplified path to create compact, connected, and production-ready solutions.

The Arduino NANO R4 board is supplied with headers that can be soldered according to your design requirements.

• Simple transition from prototype to production: leverages the RA4M1 microcontroller, already proven in the UNO R4 family, with minimal code changes.
• Compact and production-ready design: reduced dimensions of 4.5 x 1.8 cm, castellated holes, and single-sided components for easy integration into custom hardware.
• Easy expansion: the integrated Qwiic connector and the additional 5V I2C port allow for seamless connection of sensors and actuators, including Modulino nodes.
• Customizable feedback: use the programmable RGB LED to indicate system status, facilitating debugging and improving user interaction.
• Flexibility: take advantage of the Arduino ecosystem, the intuitive development environment, and the robust support community.
