Arduino nano: common questions

What microcontroller does the Arduino nano use?

The Arduino nano is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the Arduino nano PCB?

The Arduino nano measures 21 × 44.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino nano?

26 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Arduino nano design files?

From the mryashrk/Arduino-nano-pcb-design 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?

The repository has no license, so all rights stay with mryashrk. 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.
