Almost got the first one redesigned... and I got the recommended schematic from Maxim for the 6655 chip.
Should not be a problem to put two of those on there.
Boards are now exactly 1" x 1" AND I added the ground pins, the power switch and TWO SMBus+power headers to daisy chain.
The power switch will only turn off the immediate board. Power will still be provided to the chain.
Shoud be finished tomorrow.
