OpenFC: common questions
How big is the OpenFC PCB?
The OpenFC measures 26.9 × 26.9 mm, has 6 copper layers and is 1 mm thick.
How many components are on the OpenFC?
97 components, from 45 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 OpenFC design files?
From the tetraethylmethane/NIDAR-RescueSwarm 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 OpenFC design in my own project?
The repository has no license, so all rights stay with tetraethylmethane. Use it as a reference, and ask the author before reusing the design.
