Power: common questions
How big is the Power PCB?
The Power measures 119.4 × 62.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Power?
204 components, from 54 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 Power design files?
From the foxsi/UMN-boards-FOXSI-4 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 Power design in my own project?
The repository has no license, so all rights stay with foxsi. Use it as a reference, and ask the author before reusing the design.
