About the Arduino Nano PCB

Arduino Nano is an open source AVR/Arduino PCB design by sabogalc, published on GitHub under the WTFPL license. It is a 2-layer board measuring 43.2 × 17.8 mm, with 28 components from 18 distinct parts.

Its main chip is the FT232RL, from the AVR/Arduino family. Other key parts include the NCP1117-5.0_SOT223 and ATMEGA328P-MU. By type, the board carries 9 capacitors, 5 diodes, 4 connectors, 4 resistors, 3 ICs and 1 crystal.

From the project

A collection of Arduino boards recreated from scratch in KiCad. Legacy USB connectors have been replaced with USB-C where applicable.

While integrating the larger footprint of the USB-C connector, I had to adjust the silkscreen labels near the connector, but I ensured that all the necessary information remained clear and accessible.

Arduino Nano: common questions

What microcontroller does the Arduino Nano use?

The Arduino Nano is built around the FT232RL, from the AVR/Arduino family.

How big is the Arduino Nano PCB?

The Arduino Nano measures 43.2 × 17.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino Nano?

28 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Arduino Nano design files?

From the sabogalc/KiCad-Arduino-Boards 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 design in my own project?

Yes, under the terms of its WTFPL license, which sabogalc chose for the repository.

Can I test firmware for the Arduino Nano 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.
