Final cu: common questions
How big is the Final cu PCB?
The Final cu measures 200 × 300 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Final cu?
194 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the Final cu design files?
From the KN-Breadboard-Computing/computer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Final cu design in my own project?
The repository has no license, so all rights stay with KN-Breadboard-Computing. Use it as a reference, and ask the author before reusing the design.
