Pegatron schematic, revision 2, whose name lists BIC50, BA52 and CP, which appear to be project or board codes rather than a retail model. The 1.32 MB PDF suits fault-finding work such as tracing power rails, locating the source of a missing voltage and reading connector pinouts. Pegatron designs boards sold under other brands, so identify the device by the codes printed on the PCB itself. Open it in any PDF viewer and use the text search to move between sheets by net name or reference designator.
