I have received my boards, and would also like the point out the placement of the connectors.
For me if would be better if the board was delivered with the connectors un-soldered. I will mount the boards in a aluminium-chassis, and then it makes sense to connect the board with thermal paste directly to the chassis for good heat transfer.
I had to cut the termination blocks that are mounted to be able to remove them, and it’s difficult to get a new header connector into the small holes after they have been soldered once.
Also it decreases the total height of the board, because there are already big capacitors on the other side, which is good for tight spaces.
