Small 82.5 KB .cad boardview for the USB board of the NB8511 design, revision 1.0. Because it only covers the USB daughterboard, it is compact and shows the port connectors, protection parts and the cable connector to the main board. Open it in a boardview program like OpenBoardView or FlexBV to identify pins and measure continuity from a port to the connector when a port is dead. The file name gives no laptop model or brand, so check that the daughterboard marking matches NB8511 REV 1.0 before using it.
