Just my Samsung J6 mobile camera, and very close up.It might help if you showed another photo showing the entire board so that we get an idea of what else is on the board.
What is the make/model of the unit and its purpose/function?
btw, your first photo is excellent. We'd wish that all photos be as sharp as yours. What camera did you use?
the pins are M1 M2 G ... at the first post the bold connection goes to G (if it's the device not in active production/-distribution - we may never find any references to it)at the datasheet
