Questions
How big is the KTHFS DCDC PCB?
It measures 95 × 95 mm and has 4 copper layers, 1.6 mm thick.
What parts does the KTHFS DCDC use?
189 parts, built around the IXYP8N90C3, 2EDR6258XXUMA1, CL32B106KMVNNWE and C1210C562JDGACAUTO. 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 KTHFS DCDC KiCad files?
From the erikAWTO/KTHFS-DCDC repository on GitHub, at the commit this page was made from: the board is kicad/KTHFS-DCDC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the KTHFS DCDC design in my own project?
Its repository states no licence, so its author keeps all rights: ask erikAWTO before reusing the design.
