Questions
How big is the ShotClockProject PCB?
It measures 71.8 × 71.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ShotClockProject use?
107 parts, built around the TPS63000DRC, LD39015M33R, TK-6580S-2 and CY-SMD-9019-3040. 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 ShotClockProject KiCad files?
From the NeusAap/ShotClock repository on GitHub, at the commit this page was made from: the board is hw/ShotClockProject/ShotClockProject.kicad_pcb and its schematic hw/ShotClockDisplayPCB/ShotClockDisplayPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ShotClockProject design in my own project?
Its repository states no licence, so its author keeps all rights: ask NeusAap before reusing the design.
