Hi Lmichell,

I received the VU-board PCB from the manufacturer, but it is completely different from the one you have described and shown:

For example the PSU part is missing and the BOM doesn't match.

Can I still use it or do I need the bigger PCB? If its usabe, what is the schematic diagram that fits with this board?

Regards, Gerrit
