Questions
How big is the Cross table PCB?
It measures 110 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cross table use?
86 parts, built around the 24LC1025-I/P, BSS138 and MBR1020VL. 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 Cross table KiCad files?
From the cclienti/mechanics repository on GitHub, at the commit this page was made from: the board is cross-table/electronic/cross-table/cross-table.kicad_pcb and its schematic cross-table/electronic/cross-table/cross-table.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cross table design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
