Daughterboard: common questions
How big is the Daughterboard PCB?
The Daughterboard measures 42 × 39 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Daughterboard?
18 components, from 14 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 Daughterboard design files?
From the profdc9/VNA repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Daughterboard design in my own project?
The repository has no license, so all rights stay with profdc9. Use it as a reference, and ask the author before reusing the design.
