Questions
How big is the Gppr PCB?
It measures 90 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gppr use?
35 parts, built around the TPS7A470X, MURS120, 1SMB5927BT3G and IRLR2908. 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 Gppr KiCad files?
From the mgosselin/gppr repository on GitHub, at the commit this page was made from: the board is cad/gppr.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gppr design in my own project?
Its repository states no licence, so its author keeps all rights: ask mgosselin before reusing the design.
