Questions
How big is the Squale PCB?
It measures 450 × 160 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Squale use?
219 parts, built around the 74LS245SC, TL084, 74LS166AP-E and 74LS374PC. 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 Squale KiCad files?
From the jfdelnero/Apollo_7_Squale repository on GitHub, at the commit this page was made from: the board is hardware/Motherboard/Squale.kicad_pcb and its schematic hardware/Motherboard/CPU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Squale design in my own project?
Its repository states no licence, so its author keeps all rights: ask jfdelnero before reusing the design.
