Questions
How big is the 555Board PCB?
It measures 35.8 × 17.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 555Board use?
11 parts. 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 555Board KiCad files?
From the nick1076/Learning-Module-Boards repository on GitHub, at the commit this page was made from: the board is Modules/Module 1/555Board/555Board.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 555Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask nick1076 before reusing the design.
