Questions
How big is the LC meter PCB?
It measures 81.1 × 45.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LC meter use?
43 parts, built around the L7805, LM311DRG, 1N4148WX-TP and SIP-1A05D. 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 LC meter KiCad files?
From the PA2ER/LC-meter repository on GitHub, at the commit this page was made from: the board is LC-meter.kicad_pcb and its schematic LC-meter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LC meter design in my own project?
Its repository states no licence, so its author keeps all rights: ask PA2ER before reusing the design.
