Questions

How big is the MultiplexerBoard PCB?

It measures 40.5 × 26 mm and has 2 copper layers, 1.6 mm thick.

What parts does the MultiplexerBoard use?

6 parts, built around the 74HC151D,653-JSM. 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 MultiplexerBoard KiCad files?

From the nick1076/Learning-Module-Boards repository on GitHub, at the commit this page was made from: the board is Modules/MultiplexerBoard/MultiplexerBoard.kicad_pcb and its schematic Modules/Analog & Digital Servo Tester/ServoTesterBoard/ServoTesterBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the MultiplexerBoard design in my own project?

Its repository states no licence, so its author keeps all rights: ask nick1076 before reusing the design.
