Hardware: common questions
How big is the Hardware PCB?
The Hardware measures 56 × 90 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Hardware?
37 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the Hardware design files?
From the gfroerli/hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Hardware design in my own project?
The repository has no license, so all rights stay with gfroerli. Use it as a reference, and ask the author before reusing the design.
