Arduino Nano: common questions

What microcontroller does the Arduino Nano use?

The Arduino Nano is built around the ATMEGA168-20AU, from the AVR/Arduino family.

How big is the Arduino Nano PCB?

The Arduino Nano measures 46.2 × 22.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Arduino Nano?

33 components, from 19 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Arduino Nano design files?

From the RudraKumar1218/Arduino_Nano_KiCad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Arduino Nano design in my own project?

The repository has no license, so all rights stay with RudraKumar1218. Use it as a reference, and ask the author before reusing the design.

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.
