Questions
How big is the Pramp PCB?
It measures 202.7 × 128.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pramp use?
194 parts, built around the LM4562NA, NE5532, ULN2003A and 74HCT00D. 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 Pramp KiCad files?
From the tompinn23/pramp repository on GitHub, at the commit this page was made from: the board is pramp.kicad_pcb and its schematic control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pramp design in my own project?
Its repository states no licence, so its author keeps all rights: ask tompinn23 before reusing the design.
