Chassis: common questions
How big is the Chassis PCB?
The Chassis measures 80 × 80.1 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Chassis?
63 components, from 53 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 Chassis design files?
From the ut-ras/robomaster_hardware 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 Chassis design in my own project?
The repository has no license, so all rights stay with ut-ras. Use it as a reference, and ask the author before reusing the design.
