Questions
How big is the PCB power-2 PCB?
It measures 30 × 58 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB power-2 use?
23 parts, built around the LM1117DT-5.0 and IRF7303. 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 power-2 KiCad files?
From the ApolLO-CanSat/PCB-power-2 repository on GitHub, at the commit this page was made from: the board is pcb-power-2.kicad_pcb and its schematic pcb-power-2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB power-2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ApolLO-CanSat before reusing the design.
