Overview
KerbalKontrol is an open-source printed circuit board by makerforceio, from the makerforceio/KerbalKontrol repository on GitHub, published under the MIT licence. It is a 2-layer board of 81.3 × 71.1 mm with 29 parts on 58 nets, routed with 488 tracks and 64 vias.
It is built around the ATMEGA328-AU and FT232RL. Its parts include 6 capacitors, 5 resistors, 2 ICs, 2 diodes and 2 connectors. It belongs with the AVR (ATmega, ATtiny) boards of this library.

README
README.mdKerbalKontrol
Kerbal Space Program is a popular space simulator game which we at MakerForce been enjoying for a while. So, we decided to just go build an arcade like console for it. This project was fortunate enough to be featured on Hackaday [blocked], and you can check out the original blog post here.
Implementation
This control station is based fully upon the ATMEGA328 as its primary MCU. It is powered by 2 custom designed PCBs - the IO-Board and the Main-Board. The IO-Board is connected to each panel and contains a single MCU + shift registers. All of the IO-Boards are wired to the Main-Board using RJ45 conns and ethernet cables. The communication bus within is currently I2C but we want to switch to D-I2C in the future. All of the IO-Boards are configured as I2C Slaves and the Main-Board is the single master.
The internal switches, lights are wired up to the boards through the header connectors visible on the IO-Board.
Software
Everything is programmed using avr-libc with no external libraries.
Compile from source
To compile from source for the IO-Board and Main-Board, follow the steps below.
git clone https://www.github.com/solderneer/KerbalKontrol
cd code/io-board
makegit clone https://www.github.com/solderneer/KerbalKontrol
cd code/main-board
makeThe directory can simply be cleaned with this command.

Questions
How big is the KerbalKontrol PCB?
It measures 81.3 × 71.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KerbalKontrol use?
29 parts, built around the ATMEGA328-AU and FT232RL. 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 KerbalKontrol KiCad files?
From the makerforceio/KerbalKontrol repository on GitHub, at the commit this page was made from: the board is electronics/main-board/main-board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the KerbalKontrol design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
