Questions
How big is the Ignitionlet PCB?
It measures 143.5 × 43.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ignitionlet use?
142 parts, built around the MT25QL128ABB8E12-0AUT, LT3013EFE#PBF, AMPMGFB-50.0000T and SN74AUP1G08DBVR-TP. 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 Ignitionlet KiCad files?
From the oxidecomputer/hw-ignitionlet repository on GitHub, at the commit this page was made from: the board is ignitionlet.kicad_pcb and its schematic ignitionlet-config.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ignitionlet design in my own project?
Its repository publishes it under the MPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
