Boardview for the iPhone 5C, delivered as a 266 KB file in .bvr format. The name states only the model, without board number or revision. The 5C board resembles the iPhone 5 design but is not identical, so confirm the layout matches your phone. A BVR viewer lets you search reference designators, highlight nets and see where test points sit, which helps when tracing missing voltages, checking charging or audio lines and replacing damaged components. It works best alongside a matching schematic for signal names and values.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @GENERAL_SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
