ETC: common questions
How big is the ETC PCB?
The ETC measures 63.3 × 79.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ETC?
36 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the ETC design files?
From the formulaslug/fs-3-schematics repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ETC design in my own project?
The repository has no license, so all rights stay with formulaslug. Use it as a reference, and ask the author before reusing the design.
