Questions
How big is the Signals PCB?
It measures 177.8 × 127 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Signals use?
108 parts, built around the LM358N, AD7524JNZ, 74HC161S and RCJ-014. 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 Signals KiCad files?
From the clydeshaffer/gametank repository on GitHub, at the commit this page was made from: the board is Hardware/KiCad/AVBoard/signals.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Signals design in my own project?
Its repository states no licence, so its author keeps all rights: ask clydeshaffer before reusing the design.
