About the Arduino nano breakout board

Arduino nano breakout board is an open source AVR/Arduino PCB design by baleshwarece-jpg, published on GitHub. It is a 2-layer board measuring 45 × 80 mm, with 8 components from 5 distinct parts.

Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. By type, the board carries 3 capacitors, 2 connectors, 1 module, 1 diode and 1 resistor.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

30-Days-PCB-Design-Challenge

The Arduino Nano Extension Board is a simple yet highly practical PCB designed to transform the Arduino Nano into a more accessible and organized development platform. Rather than connecting sensors and modules directly to the Nano's tightly packed headers, this board expands every I/O pin into clearly labeled breakout connections, simplifying wiring, debugging, and rapid prototyping.

Arduino nano breakout board: common questions

What microcontroller does the Arduino nano breakout board use?

The Arduino nano breakout board is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Arduino nano breakout board?

The Arduino nano breakout board measures 45 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino nano breakout board?

8 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Arduino nano breakout board design files?

From the baleshwarece-jpg/PCB_PROJECTS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Arduino nano breakout board design in my own project?

The repository has no license, so all rights stay with baleshwarece-jpg. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Arduino nano breakout board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
