850: common questions
How big is the 850 PCB?
The 850 measures 65 × 106.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 850?
238 components, from 74 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 850 design files?
From the minisystem/850 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the 850 design in my own project?
The repository has no license, so all rights stay with minisystem. Use it as a reference, and ask the author before reusing the design.
