Questions

How big is the PCBProject PCB?

It measures 151 × 68.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PCBProject use?

49 parts, built around the HLK-PM12, CD4026BE, NE555D and CD4007UBE. 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 PCBProject KiCad files?

From the aditya02095/PCB-Design repository on GitHub, at the commit this page was made from: the board is PCB_Design/PCBProject/PCBProject.kicad_pcb and its schematic PCB_Design/PCB Project/PCBProject.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PCBProject design in my own project?

Its repository states no licence, so its author keeps all rights: ask aditya02095 before reusing the design.
