Problem is, I have no idea, which way the VR plugs into the V0.37 PCB raised headers. It has "top" & "bottom", labelled on it, so I assume "bottom" faces the V0.37 PCB. However, it can be orientated laterally, two ways.
Which way does it fit to the main board ? Also, what is the jumper J1 used for on the VR conditioner. Can't seem to find any reference to it, in the literature.
