Arduino® Nano R4 with headers
The Arduino Nano R4 with headers brings the robust performance of the RA4M1 microcontroller into the beloved Nano form factor, offering a compact, ready-to-use solution for embedded development, creative prototyping, and educational projects.
Overview
Nano R4 merges Arduino’s signature ease of use with the powerful Renesas RA4M1 microcontroller and a range of embedded features – the pinout includes CAN, DAC, VRTC and OpAmp! – enabling effortless scaling from prototyping on the UNO R4 to production-ready applications.
With pre-soldered headers, the Nano R4 is ready out of the box for breadboarding, connecting to Modulino nodes, and jumping into experimentation without additional assembly. It maintains the same pinout as other boards in the Nano family and features an on-board Qwiic connector for rapid sensor and peripheral expansion, as well as a programmable RGB LED for intuitive system feedback. Its single-sided component design makes it ideal for space-constrained products, ensuring a seamless transition from classroom or 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 students, designers, and developers a streamlined path to build compact, connected, and production-ready solutions.
Key benefits
- Effortless transition from prototyping to production: Leverage the RA4M1 microcontroller already trusted in the UNO R4 family, with minimal code adjustments needed.
- Compact, production-ready design: Tiny 4.3 x 1.7 cm footprint, castellated pins, and single-sided components facilitate easy integration into custom hardware.
- Plug-and-play prototyping: With pre-soldered headers, it’s easy to jump into breadboarding, testing, and connecting external modules like Modulino nodes.
- Easy expansion: The built-in Qwiic connector and additional 5V I2C port allow seamless connectivity to a wide range of sensors and actuators.
- Customizable feedback: Use the programmable RGB LED to indicate system states for faster debugging and smarter user interaction.
- Flexible, familiar platform: Enjoy Arduino’s rich ecosystem, intuitive development environment, and robust community support.
Application examples to explore
- Educational and creative prototyping: Tech students and designers can rapidly develop and test interactive installations, product concepts, or course projects with minimal setup.
- Embedded industrial systems: Thanks to its compact design and production-ready features, the Nano R4 is ideal for creating embedded industrial solutions where space is limited but reliability is critical.
- Home automation: With easy sensor and actuator integration, the Nano R4 enables fast development of connected and smart products that make your daily life easier.
- Robotics and automation projects: The small footprint and robust connectivity make it perfect for miniaturized robots, autonomous devices, or interactive art.
