Questions
How big is the Logic Level Bidirectional PCB?
It measures 15.2 × 12.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Logic Level Bidirectional use?
18 parts, built around the 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 Logic Level Bidirectional KiCad files?
From the crazyelectron-io/Logic_Level_Bidi repository on GitHub, at the commit this page was made from: the board is Hardware/KiCAD/Logic_Level_Bidirectional.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Logic Level Bidirectional design in my own project?
Its repository states no licence, so its author keeps all rights: ask crazyelectron-io before reusing the design.
