Questions
How big is the Scratch-001 PCB?
It measures 65 × 64.5 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Scratch-001 use?
114 parts, built around the LP5912-1.8DRV, SN74AVC16T245DGGR-JSM, TPS651851RSLR and TPS7A2533DRV. 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 Scratch-001 KiCad files?
From the CrypticRage/scratch-001 repository on GitHub, at the commit this page was made from: the board is scratch-001.kicad_pcb and its schematic connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scratch-001 design in my own project?
Its repository states no licence, so its author keeps all rights: ask CrypticRage before reusing the design.
