Addon board: common questions

What microcontroller does the Addon board use?

The Addon board is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the Addon board?

The Addon board measures 78.6 × 84.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Addon board?

22 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 Addon board design files?

From the b1uN7/DEFCON-26-Flying-Skull-Badge repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Addon board design in my own project?

The repository has no license, so all rights stay with b1uN7. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Addon board 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.
