PCB layer file for the Steam Deck OLED mainboard DA0F7GMBAE0, revision E, in a zip archive. The Quanta-style DA number identifies the ODM design, with F7G as the project code. Layer data shows the copper on individual board layers, which helps follow traces hidden under components, check routing between pads and plan jumper wire repairs after corrosion or pad damage. Open it with a viewer that supports the included format, and match the revision E marking on your board before tracing anything critical.
