Questions
How big is the PCB DESIGN PCB?
It measures 76.2 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB DESIGN use?
17 parts, built around the TL072, LM393, IRF4905 and IRLZ44N. 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 PCB DESIGN KiCad files?
From the HarshSharma2412/PCB-DESIGN repository on GitHub, at the commit this page was made from: the board is PCB.kicad_pcb and its schematic SCHEMATIC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB DESIGN design in my own project?
Its repository states no licence, so its author keeps all rights: ask HarshSharma2412 before reusing the design.
