Questions
How big is the DCConverter PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DCConverter use?
25 parts, built around the TPS5450DDAR, B540C and SMBJ30A. 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 DCConverter KiCad files?
From the aswinsantdeu/CircuitsAndPCBDesigns repository on GitHub, at the commit this page was made from: the board is Kicad/DCConvertor/DCConverter.kicad_pcb and its schematic Kicad/DCConvertor/DCConverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCConverter design in my own project?
Its repository states no licence, so its author keeps all rights: ask aswinsantdeu before reusing the design.
