AIUI, the pins numbered 27, 29, 31 are the Ground, Rx, and Tx pins for the Marvell MCU's serial console, not necessarily in that order.

The remaining pins in the 12-pin header are for LEDs and pushbutton switches for those models that support them.

The two pins on the left appear to be the (C)athode and (A)node terminals of an indicator LED.
