Questions
How big is the TopPcbV2 PCB?
It measures 101.3 × 90.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TopPcbV2 use?
35 parts, built around the 218-2LPSTR, SS34, VLS6045EX-470M-CA and XPGDWT-B1-0000-00LE1. 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 TopPcbV2 KiCad files?
From the AaronWiersma/LoiterGuardTopPcb repository on GitHub, at the commit this page was made from: the board is TopPcbV2.kicad_pcb and its schematic TopPcbV2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TopPcbV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask AaronWiersma before reusing the design.
