PSU: common questions
How big is the PSU PCB?
The PSU measures 190 × 160 mm, has 4 copper layers and is 1.66 mm thick.
How many components are on the PSU?
56 components, from 24 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the PSU design files?
From the skylar-slideshows/Digilog_Capstone repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the PSU design in my own project?
The repository has no license, so all rights stay with skylar-slideshows. Use it as a reference, and ask the author before reusing the design.
