Sdfsdf: common questions
How big is the Sdfsdf PCB?
The Sdfsdf measures 80 × 60 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Sdfsdf?
17 components, from 7 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 Sdfsdf design files?
From the lightningspore/seedsigner-luckfox-pico 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 Sdfsdf design in my own project?
The repository has no license, so all rights stay with lightningspore. Use it as a reference, and ask the author before reusing the design.
