Questions
How big is the Distribution PCB?
It measures 30 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Distribution use?
12 parts, built around the OKL-T/3-W12N-C, B3B-ZR and B2PS-VH. 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 Distribution KiCad files?
From the lipoyang/StackChanPwd repository on GitHub, at the commit this page was made from: the board is boards/Distribution/Distribution.kicad_pcb and its schematic boards/Bridge/Bridge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Distribution design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
