The Arduino Nano R4 delivers the trusted performance of the Renesas RA4M1 microcontroller in the beloved Nano form factor, making it the ultimate compact solution for embedded development, creative prototyping, and education. With pre-soldered headers, you can jump straight into breadboarding, testing, and connecting external modules like Modulino nodes. It features a Qwiic connector for rapid sensor expansion and a programmable RGB LED for intuitive system feedback. Compatible with the Arduino IDE and libraries (including Arduino UNO R4 Minima), this board offers students, designers, and developers a flexible and familiar platform to build compact, connected, and scalable solutions. Whether you're working on interactive installations, miniaturized robotics, or industrial systems, the Nano R4 with headers accelerates the path from idea to prototype.
