Questions
How big is the UnfolderBuffer PCB?
It measures 135 × 92 mm and has 4 copper layers, 1.6 mm thick.
What parts does the UnfolderBuffer use?
189 parts, built around the LTC1144CS8, LTC2050CS8, TPS562200DDC and HSEC8-130-01-L-DV-A. 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 UnfolderBuffer KiCad files?
From the kefernandez/SSB_ChargeInjection repository on GitHub, at the commit this page was made from: the board is UnfolderBuffer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UnfolderBuffer design in my own project?
Its repository states no licence, so its author keeps all rights: ask kefernandez before reusing the design.
