Questions
How big is the JBC controller PCB?
It measures 70 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the JBC controller use?
42 parts, built around the AD8538ARZ, LM1117-3.3, FSMRA3JH and BC846. 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 JBC controller KiCad files?
From the microbug/soldering-station repository on GitHub, at the commit this page was made from: the board is Hardware/JBC controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the JBC controller design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
