The Official Arduino Nano R4 ABX00142 (Made in Italy) is a compact, production-ready microcontroller board designed to bridge the gap between rapid prototyping and scalable product development. Powered by the Renesas RA4M1 microcontroller, the same MCU family used in the Arduino UNO R4 series, the Nano R4 delivers high performance, reliability, and long-term design consistency in a small Nano-form-factor footprint. Available from BDTronics, this board is ideal for embedded systems, industrial control, robotics, and compact IoT applications.

Designed with castellated edges and a single-sided component layout, the Nano R4 is optimized for direct SMD mounting onto custom PCBs, making it perfect for professional hardware integration. It maintains full pin compatibility with the classic Arduino Nano lineup while introducing modern features such as a built-in Qwiic connector, programmable RGB LED, and enhanced I2C connectivity. Developers can reuse existing Arduino libraries and workflows while benefiting from improved performance and long-term scalability.

The Arduino Nano R4 offers seamless compatibility with the Arduino ecosystem and UNO R4 software environment, enabling faster development cycles and easier migration from prototypes to production-ready devices. BDTronics provides the original Made in Italy Nano R4 for developers, engineers, startups, and educators seeking reliable and future-proof embedded solutions.
