- This is the KiCAD Projects Repository.
- I recommend not to use these KiCAD data.
- Some projects are unfinished or have issues in the circuit.
- I designed these circuits based on whether I can solder them, not on whether the average person can.

Questions
How big is the Dcdc PCB?
It measures 40 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dcdc use?
15 parts, built around the LM358, 2SA1015 and 2SC1815. 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 Dcdc KiCad files?
From the Tert2/KiCAD repository on GitHub, at the commit this page was made from: the board is dcdc/dcdc/dcdc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dcdc design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tert2 before reusing the design.
