README
README.mdNEMO Documentation
Welcome to NEMO—the NMEA2000 Education and Maritime Operations Platform.
NEMO is a research platform for exploring at maritime network security. It simulates sensors, sniffs traffic, and demonstrates just how easy you can mess with NMEA2000.
This platform focuses on lowering the bar for getting started with boat hacking. Typically to get started with boat hacking you would need thousands of dollars worth of equipment or a friend with a boat. Thankfully, with NEMO all you need is about 40 dollars.

Questions
How big is the NEMO PCB?
It measures 108 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NEMO use?
13 parts. 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 NEMO KiCad files?
From the Soups71/NEMO repository on GitHub, at the commit this page was made from: the board is PCB/NEMO.kicad_pcb and its schematic PCB/NEMO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NEMO design in my own project?
Its repository states no licence, so its author keeps all rights: ask Soups71 before reusing the design.
