Questions
How big is the Slave Board PCB?
It measures 81.3 × 358.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Slave Board use?
101 parts, built around the LPC11C24FBD48/30EL, BD9E302EFJ-E2, SN74LVC8T245PW and NCP718ASN330. 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 Slave Board KiCad files?
From the jayalcock/Clocks repository on GitHub, at the commit this page was made from: the board is hardware/slave-board/Slave Board.kicad_pcb and its schematic hardware/archive/Main Board V0/Main Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Slave Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jayalcock before reusing the design.
