TT: common questions
How big is the TT PCB?
The TT measures 183 × 128.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the TT?
174 components, from 40 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 TT design files?
From the seismicindustries/TT repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the TT design in my own project?
The repository has no license, so all rights stay with seismicindustries. Use it as a reference, and ask the author before reusing the design.
