Arduino Nano R4 [ABX00142] Headers Not Mounted (Loose Pins Included), Compact Renesas RA4M1 Microcontroller Board, Qwiic Connector, Programmable RGB LED, Compatible IDE

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. This version ships with loose male headers you can solder for breadboarding, or you can take advantage of the castellated edges to reflow-solder the board directly onto your custom PCB. It also features a Qwiic connector for rapid sensor expansion and a programmable RGB LED for intuitive system feedback. The single-sided design and castellated edges make it ideal for embedding into space-constrained, production-ready applications. 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.

• POWERFUL PERFORMANCE IN NANO FORM FACTOR – Built on the robust Renesas RA4M1 microcontroller with 256KB flash, 32KB RAM, and a 48MHz clock speed for advanced embedded applications.
• FLEXIBLE INTEGRATION OPTIONS – Ships with loose male header pins that you can solder for breadboard prototyping, or use the castellated edges to mount the board directly onto a custom PCB.
• SEAMLESS CONNECTIVITY – Includes a Qwiic connector and additional 5V I²C port for effortless expansion with sensors, actuators, and peripherals.
• CUSTOMIZABLE SYSTEM FEEDBACK – Onboard programmable RGB LED helps streamline debugging and user interaction in your projects.
• IDEAL FOR EDUCATION & PRODUCTION – With its tiny 4.3 × 1.7 cm footprint, single-sided components, and castellated edges, it’s perfect for both prototyping and embedding in custom PCBs.
