Analog: common questions
How big is the Analog PCB?
The Analog measures 42.8 × 17.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Analog?
21 components, from 19 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 Analog design files?
From the TZeng0698/Portable-EEG-with-Modular-Pre-Filtering-for-BCI-Applications 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 Analog design in my own project?
The repository has no license, so all rights stay with TZeng0698. Use it as a reference, and ask the author before reusing the design.
