Questions
How big is the Shift register control panel PCB?
It measures 68.2 × 41.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shift register control panel use?
33 parts, built around the 74HC14, 74HC595 and LM7805. 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 Shift register control panel KiCad files?
From the EHMD28/shift-register-control-panel repository on GitHub, at the commit this page was made from: the board is src/shift-register-control-panel.kicad_pcb and its schematic src/shift-register-control-panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shift register control panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask EHMD28 before reusing the design.
