AirBoxnano: common questions

What microcontroller does the AirBoxnano use?

The AirBoxnano is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the AirBoxnano PCB?

The AirBoxnano measures 44 × 21 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AirBoxnano?

30 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 AirBoxnano design files?

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

Can I use the AirBoxnano design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which danfei chose for the repository.

Can I test firmware for the AirBoxnano 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.
