Svm: common questions
How big is the Svm PCB?
The Svm measures 148 × 38.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Svm?
44 components, from 20 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 Svm design files?
From the lucia3e8/emgsvm 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 Svm design in my own project?
The repository has no license, so all rights stay with lucia3e8. Use it as a reference, and ask the author before reusing the design.
