Questions
How big is the CPU Board PCB?
It measures 100 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CPU Board use?
116 parts, built around the A2235-H, INA128U, FT232RL and HTS221. 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 CPU Board KiCad files?
From the jsjolund/sailoraid repository on GitHub, at the commit this page was made from: the board is Hardware/CPU_Board_rev2/CPU_Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CPU Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jsjolund before reusing the design.
