Questions
How big is the Jlctest PCB?
It measures 121 × 75.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Jlctest use?
46 parts, built around the SP485EEN-L, LM324DT, NE5532DR-MS and OP07CDRG. 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 Jlctest KiCad files?
From the cjheath/jlcbasic repository on GitHub, at the commit this page was made from: the board is jlctest/jlctest.kicad_pcb and its schematic jlctest/jlctest.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jlctest design in my own project?
Its repository states no licence, so its author keeps all rights: ask cjheath before reusing the design.
