README
README.md💥OpenPCB: Manufacturing Double Layer PCBs Using Commodity Laser Engraver💥
This guide shows you how to manufacture a double layer PCB with vias and through holes using a relatively low cost (<$2k) commodity fiber laser engraver (ComMarker B4 20W). We provide custom enclosure design files to improve the safety of the engraver as well as 3D-printable clamp rigs to enable repeatable lasing operations on both sides of the PCB with minimal tuning.

Questions
How big is the PeakDetector Breakout PCB?
It measures 26 × 18.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PeakDetector Breakout use?
10 parts. 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 PeakDetector Breakout KiCad files?
From the S4-Lab/OpenPCB repository on GitHub, at the commit this page was made from: the board is ExampleDesign/KiCAD/PeakDetector_Breakout/PeakDetector_Breakout.kicad_pcb and its schematic ExampleDesign/KiCAD/PeakDetector_Breakout/PeakDetector_Breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PeakDetector Breakout 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).
