The labeling of the outputs on these boards has always confused me. Electrically, it seems like there are two inputs (+, -) and two outputs (V+/-, gnd). But the labeling has more names for these four points. For example:
The positive input has D+, D++, and D+++, but also three connection points for "ST_IN1".
The output has V+, V++, and V+++, as well as ST_+, and three more connections labeled "1, 2, 3"
On the ground side, there is the "ST_G1" set of connections, as well as one labeled "GND2.2"
I assume there are meanings to the various sets of connections, but I don't understand what they are. Is "V+++" better than "V+"? Is there a difference between "GND2.2" and "ST_G1"?
I know these are stupid questions, but please have patty on me 😱

This are not really standard practice, but the board is intended to serve for a variety of uses.
Each connection has to have a unique label that distinguishes it from the others, for instructional
and troubleshooting purposes. It should be in the build guide somewhere.

There are some pictures showing how they are used, but no real explanation about *why* they are used that way. Also, some of the things he does confuse me, like tying the boards together at ST_IN2/3. Isn't that connecting the + and - channels from the rectifiers together? Wouldn't that cause a short?
That may be the series connection for a center tap secondary winding, not sure.
There should be a list of these codes and an explanation. I would just use this schematic.

Yes, that is the schematic I am using. I have not seen such a list with an explanation, that is why I made this thread. I wish the build guides were more clear about this stuff, there is a lot of hand waving at the lower levels that skips over this sort of thing.
Looks like joj818 designed the board and/or the schematic, you could try contacting him.
