From the project

Aerospace Village Badge 2020

This resository is to document and capture all of the engineering and design work that went into creating the Aerospace Village Badge for 2020.

The badge is a multifunctional design that is part SWAG, part antenna, part low level protocol interaction. In keeping with the spirit of aviation everything is as small as possible and tries to use as much of the available resources as possible.

AvBadge 2020: common questions

What microcontroller does the AvBadge 2020 use?

The AvBadge 2020 is built around the ATtiny85-20SU, from the AVR/Arduino family.

How big is the AvBadge 2020 PCB?

The AvBadge 2020 measures 134.3 × 140 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AvBadge 2020?

20 components, from 13 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 AvBadge 2020 design files?

From the AerospaceVillage/avBadge_2020 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 AvBadge 2020 design in my own project?

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

Can I test firmware for the AvBadge 2020 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.
