Questions
How big is the FishShocker9000 PCB?
It measures 140 × 285.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FishShocker9000 use?
206 parts, built around the SN754410NE, MP2331HGTL-Z, DEV-16771 and P70-1000045R. 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 FishShocker9000 KiCad files?
From the rmranjitkarNULL/FishShocker9000 repository on GitHub, at the commit this page was made from: the board is PCB/FishShocker9000_PCB/FishShocker9000.kicad_pcb and its schematic PCB/FishShocker9000_PCB/FishShocker9000.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FishShocker9000 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rmranjitkarNULL before reusing the design.
