Questions
How big is the Crossfire mk1 PCB?
It measures 59.6 × 57.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Crossfire mk1 use?
73 parts, built around the RP2040, RT6154AGQW and ABM8-272-T3. 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 Crossfire mk1 KiCad files?
From the lightsource-nz/crossfire repository on GitHub, at the commit this page was made from: the board is pcb/crossfire_mk1.kicad_pcb and its schematic pcb/crossfire.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Crossfire mk1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lightsource-nz before reusing the design.
