Questions
How big is the Hydra PCB?
It measures 97.8 × 36.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hydra use?
27 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 Hydra KiCad files?
From the d3cker/HydraPCB repository on GitHub, at the commit this page was made from: the board is hydra.kicad_pcb and its schematic hydra.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hydra design in my own project?
Its repository states no licence, so its author keeps all rights: ask d3cker before reusing the design.
