Questions
What parts does the Front panel test jig use?
65 parts, built around the NC7WZ16P6X, FT231XQ-R, USBLC6-2P6 and MPZ1608S101ATAH0. 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 Front panel test jig KiCad files?
From the i2pi/scion_front_panel repository on GitHub, at the commit this page was made from: the board is scion-front-panel/front-panel-test-jig/front-panel-test-jig.kicad_pcb and its schematic scion-front-panel/blinken.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Front panel test jig design in my own project?
Its repository states no licence, so its author keeps all rights: ask i2pi before reusing the design.
