Questions
How big is the Jar light PCB?
It measures 12.2 × 40.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Jar light use?
37 parts, built around the ZXGD3005E6TA, BAT46 and SI3476DV. 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 Jar light KiCad files?
From the jonnydyer/jar_light repository on GitHub, at the commit this page was made from: the board is Rev_B/jar_light.kicad_pcb and its schematic Rev_A/jar_light.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jar light design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonnydyer before reusing the design.
