Questions
How big is the SyncFix64 PCB?
It measures 30.5 × 12.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SyncFix64 use?
16 parts, built around the LM1881, AMS1117-5.0S and BSS138. 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 SyncFix64 KiCad files?
From the hackup/SyncFix64 repository on GitHub, at the commit this page was made from: the board is SyncFix64.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SyncFix64 design in my own project?
Its repository states no licence, so its author keeps all rights: ask hackup before reusing the design.
