Dagu Explorer PCB Power

Hi,

Bought the Dagu Explorer PCB and I am a bit confused about the power supply connection underneath. There seems to be 2 options on the board I receieved but it is not consistent with some of the guide documents and I don't want to fry the board or any other bits.

The underside has a white socket - JST-XH I think from researching it but I don't have the corresponding plug. There is also a blue 2 terminal screw connector on the underside. This is not shown on the guide or other instructions.

Can anyone advise if the blue screw connector is an alternative way of supplying the battery power to the board?

Cheers, Baldrick.
