Nano R4 with Headers (ABX00143)
Introduction
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.
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.
