Charging: common questions

How big is the Charging PCB?

The Charging measures 80 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Charging?

49 components, from 20 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 Charging design files?

From the LSUTigerRacing/Electronics repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Charging design in my own project?

The repository has no license, so all rights stay with LSUTigerRacing. Use it as a reference, and ask the author before reusing the design.
