Questions
How big is the Clk rst gen PCB?
It measures 93 × 50 mm and has 2 copper layers, 1.69 mm thick.
What parts does the Clk rst gen use?
21 parts, built around the 74LS14PC. 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 Clk rst gen KiCad files?
From the tdrinfinity/turtle-pcb repository on GitHub, at the commit this page was made from: the board is clk_rst_gen/clk_rst_gen.kicad_pcb and its schematic alu/alu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clk rst gen design in my own project?
Its repository states no licence, so its author keeps all rights: ask tdrinfinity before reusing the design.
