Questions
How big is the Qpcb PCB?
It measures 280 × 205 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Qpcb use?
257 parts, built around the LT1632CS8#PBF, TPS5450QDDARQ1, MC34063ADG4 and LT3083EQ#PBF. 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 Qpcb KiCad files?
From the leonardobove/qpcb repository on GitHub, at the commit this page was made from: the board is hardware/qpcb/kicad/qpcb.kicad_pcb and its schematic hardware/amplifier/kicad/amplifier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Qpcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask leonardobove before reusing the design.
