The production pc boards for the '650 are in sets of 4 pc boards,
called an 'array'. Some folks refer to this as "step and repeat".

Here are the front and rear views of stuffed boards as I get
them from the subcontractor. The LEDs are not soldered, I do that
because it's very labor intensive and simply don't want to pay for it.

The individual boards have what's called 'scoring tabs' so that they
can be snapped apart.

10 points for the first person to correctly identify (in general) what
RV1 is and why it's on the board.
