APPS: common questions
How big is the APPS PCB?
The APPS measures 77 × 62.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the APPS?
33 components, from 25 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 APPS design files?
From the MADHURAMAN-afk/FSAE-TEAM-URJA-25-LV-circuits-and-documents 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 APPS design in my own project?
The repository has no license, so all rights stay with MADHURAMAN-afk. Use it as a reference, and ask the author before reusing the design.
