Electroscope: common questions
How big is the Electroscope PCB?
The Electroscope measures 26.9 × 29 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Electroscope?
19 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the Electroscope design files?
From the konspyre/electroscope repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Electroscope design in my own project?
The repository has no license, so all rights stay with konspyre. Use it as a reference, and ask the author before reusing the design.
