Questions
How big is the Octov1.1 PCB?
It measures 60 × 95.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Octov1.1 use?
89 parts, built around the W25Q128JVSIQ, RT9080-33GJ5, TPS61022 and DT1042-04SO-7-ES. 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 Octov1.1 KiCad files?
From the r-bt/Useless-Box-PCB repository on GitHub, at the commit this page was made from: the board is octov1.1.kicad_pcb and its schematic io.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Octov1.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask r-bt before reusing the design.
