Pressure: common questions
How big is the Pressure PCB?
The Pressure measures 40 × 33 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pressure?
27 components, from 13 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 Pressure design files?
From the cuspaceflight/m3-avionics repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Pressure design in my own project?
The repository has no license, so all rights stay with cuspaceflight. Use it as a reference, and ask the author before reusing the design.
