Questions
How big is the DCPower PCB?
It measures 80 × 50 mm and has 6 copper layers, 1.6 mm thick.
What parts does the DCPower use?
112 parts, built around the LMR33630CDDA, CYPD3177-24LQXQ, LTC4417CUF#PBF and USBLC6-2SC6. 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 DCPower KiCad files?
From the Alex-C-EE/DCPower repository on GitHub, at the commit this page was made from: the board is DCPower/DCPower.kicad_pcb and its schematic DCPower - Simple/DCPower - Simple.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCPower design in my own project?
Its repository states no licence, so its author keeps all rights: ask Alex-C-EE before reusing the design.
