Questions
How big is the DCStamp PCB?
It measures 37 × 33.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DCStamp use?
74 parts, built around the TPS65130RGE. 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 DCStamp KiCad files?
From the jeandet/DCStamp repository on GitHub, at the commit this page was made from: the board is DC-Stamp.kicad_pcb and its schematic Analog_power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCStamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask jeandet before reusing the design.
