Questions
How big is the WarpSE PCB?
It measures 112.1 × 102.1 mm and has 4 copper layers, 1.61 mm thick.
What parts does the WarpSE use?
146 parts, built around the 74LVC1G125GW, CH340G, 74AHCT573PW and 74LVC1G32GW. 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 WarpSE KiCad files?
From the garrettsworkshop/WarpSE repository on GitHub, at the commit this page was made from: the board is WarpSE.kicad_pcb and its schematic Buf.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WarpSE design in my own project?
Its repository states no licence, so its author keeps all rights: ask garrettsworkshop before reusing the design.
