Questions
How big is the Detector PCB?
It measures 39.6 × 23.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Detector use?
52 parts, built around the LP5907, LPC11U68JBD64E and 2N7002P. 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 Detector KiCad files?
From the Ttl/detector repository on GitHub, at the commit this page was made from: the board is hardware/detector/detector.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Detector design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ttl before reusing the design.
