Questions
How big is the LLTB PCB?
It measures 59.7 × 63.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LLTB use?
8 parts. 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 LLTB KiCad files?
From the wrickert/UntitledElectronics repository on GitHub, at the commit this page was made from: the board is SAO/LLTB/LLTB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LLTB design in my own project?
Its repository states no licence, so its author keeps all rights: ask wrickert before reusing the design.
