The Arduino Nano R4 brings the performance of the Renesas RA4M1 (Arm Cortex-M4 @ 48MHz) to the beloved Nano form factor — in a compact 45×18mm footprint, production-ready from day one. With a built-in Qwiic connector, castellated pins, and single-sided component design, it is the ideal solution for embedding in custom PCBs, industrial applications, and prototypes that scale to final products.

  • ⚙️ Renesas RA4M1, Arm Cortex-M4 @ 48MHz — same MCU as the UNO R4
  • 🔌 Qwiic connector for rapid sensor & Modulino node expansion
  • 📐 45×18mm — classic Nano form factor with castellated pins for SMD
  • 🎨 Programmable RGB LED for intuitive system feedback
  • 🇨🇾 Fast shipping within Cyprus — no weeks-long waits from overseas

 

Arduino Nano R4 — Compact, Production-Ready Board with Renesas RA4M1

The Arduino Nano R4 (SKU: ABX00142) combines the power of the Renesas RA4M1 microcontroller — trusted in the UNO R4 family — with the iconic Nano form factor at just 45×18mm. Designed for a seamless transition from prototyping to production, the Nano R4 features castellated pins and a single-sided layout that makes it ideal for integration into custom carrier boards and industrial applications.

Who is it for?

  • Advanced students & engineers: Already working with the Arduino UNO R4? The Nano R4 uses the same RA4M1 MCU — transfer your sketch with minimal pinout adjustments. Ideal for advanced robotics, IoT, and edge computing projects in a compact form.
  • Makers & prototypers scaling to production: The single-sided design and castellated pins allow direct SMD placement on a custom PCB — the smoothest path from breadboard prototype to finished product.
  • Industrial & embedded applications: CAN bus, dual I2C, OpAmp, and VRTC make the Nano R4 suitable for embedded systems, home automation nodes, and compact robotics where space is a critical factor.

Frequently Asked Questions

Is my Arduino UNO R4 Minima sketch compatible with the Nano R4?
Yes. The Nano R4 uses the same Renesas RA4M1 microcontroller, so sketches for the UNO R4 Minima are compatible — you only need to adjust the pinout to match the Nano form factor.

What is the difference between the Nano R4 and the classic Arduino Nano (A000005)?
The Nano R4 features a far more powerful MCU (RA4M1 Cortex-M4 @ 48MHz vs ATmega328P @ 16MHz), much more memory (256kB Flash vs 32kB), CAN bus, OpAmp, DAC, a Qwiic connector, and USB-C. It retains full pinout compatibility with existing Nano shields and hardware.

Why does the Nano R4 (ABX00142) come without headers?
The headerless version is aimed at advanced users who want to integrate the board into a custom PCB via SMD soldering or castellated pin connections. If you want to use it on a breadboard for prototyping, choose the Arduino Nano R4 with Headers variant instead.
