Oukitel C16 pro

[Colin Barrett]

Hi. I'm not sure if i'm in the right place for this but I'm gonna ask anyway.

I've got an Oukitel c16 pro and I'm trying to identify the GND point on the board. I've attached a picture of the actual board:

Please can someone help!!!

From my experience perforations/slots, that have metal on both sides, are typically part of a grounding plane. Looks like there's no meaningful stenciling on the board unless it's on the bottom.
