Questions
How big is the Salt booklamp PCB?
It measures 45.1 × 45.1 mm and has 4 copper layers, 0.8 mm thick.
What parts does the Salt booklamp use?
32 parts, built around the EMK105BJ105KV-F, RC0402JR-0710KL, SMS1105UWDW and CRCW04020000Z0ED. 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 Salt booklamp KiCad files?
From the tedfernau/SaltGlow repository on GitHub, at the commit this page was made from: the board is pcb/salt_booklamp.kicad_pcb and its schematic build/build7/Interposer/Interposer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Salt booklamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask tedfernau before reusing the design.
