Questions
How big is the HydraFlasher KiCAD PCB?
It measures 93 × 121 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HydraFlasher KiCAD use?
47 parts, built around the SN74AHCT1G125DBVR(UMW), AMS1117-3.3, WS2812B and CC0805MKX5R8BB226. 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 HydraFlasher KiCAD KiCad files?
From the Waffelo/HydraFlasher_PCB repository on GitHub, at the commit this page was made from: the board is HydraFlasher_KiCAD.kicad_pcb and its schematic HydraFlasher_KiCAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HydraFlasher KiCAD design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
