Questions
How big is the Zibs Saber v2 PCB?
It measures 20 × 160 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Zibs Saber v2 use?
75 parts, built around the ESP32-WROOM-32E-N8, MAX98357AETE+T, TPS54560BDDAR and S8205A. 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 Zibs Saber v2 KiCad files?
From the PedroBMedeiros/PolySaber repository on GitHub, at the commit this page was made from: the board is PolySaberFinalKicad/Zibs_Saber_v2.kicad_pcb and its schematic PolySaber/PolySaber.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zibs Saber v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask PedroBMedeiros before reusing the design.
