README
README.mdOverview
This repository contains miscellaneous schematics and PCB layouts. Some are projects I have built (or designed with intent to build, but decided not to build for one reason or another) and others were simple exercises for learning the design tools.
I will try to keep READMEs up-to-date in each project describing which each one is and, if the design was built, how it went.
Currently all design files are for gEDA, but I will likely experiment with other tools soon too.
(Un)license
All designs are free to use (I release them to the public domain) - see the file UNLICENSE for more details, including the oh-so-important disclaimer of warrantees.
BOMs
Several projects include BOMs, but not in the traditional pile-of-excel style. They are Haskell source files, describing the BOM and providing functions to analyze and extract information from them. They are mainly meant for my own personal use and I may change them without notice, so I'm not going to write any documentation now but feel free to ask for help if you'd like to use them.

Questions
How big is the Xmega a4u target PCB?
It measures 50.8 × 17.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Xmega a4u target use?
97 parts, built around the ATXMEGA128A4U-MH, TPD2E001IDRLRQ1 and TSX-3225. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Xmega a4u target KiCad files?
From the mokus0/schematics repository on GitHub, at the commit this page was made from: the board is xmega-a4u-target-v2/xmega-a4u-target.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Xmega a4u target design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
