Reduce number of 5v pins #21

Right now we have 6x 5v pins in two groups. Seems overkill and kind of a mistake.

Suggest we kill the top two image

4 pins for a 12A total is still overkill but given this is the critical analog sensing voltage....

Existing base boards can have a very easy trace cut to isolate the 2 pins getting eliminated. Existing brain boards can be neutered by removing those two pins. Don't really see any downside to this?

The regulator chips are limited to 150mA each, anything more than a single pin each is overkill

Yep. Only reason I can think for having two is to ensure a good connection no matter what.

Removed the center 2 and marked them "NO CONN", Actually not connected to anything on the brain right now image
