Does anyone know what the unlabelled white-plastic shrouded 4-pin connector located just above above the two USB2 headers (labelled 12 and 13 below) is for?

thx.

    Hello,
    Do you see a marking near this connector?

    Absolutely nowhere near the connector is "WIFI_BT_LED1", which returns a single hit for a different board using the same connector shroud; so apparently it's a WiFi and Bluetooth activity indicator :-/

    usually that is  ATX 12V socket. Provides additional power to the CPU.Your CPU apparently doesn't need more power.

    Thanks for the suggestion, but no it's not the ATX 12v, that's up at position 2 in the picture. The connector is 4-pin SIL (like you might expect for a fan header or PC speaker connection), but with an unusual shroud.

    Just in case anyone is searching for this information in future, the connector is providing buffered versions of the LED_WLAN and LED_WPAN signals from the Mini PCIe socket on the board, i.e. providing support for activity LEDs for the Mini PCIe WiFi card.
