OK, how does this sound:
I run all of my sensors off of the aux 5A v.reg and attach a small
heatsink (radioshack part # 276-1368) with thermal epoxy for good
measure. The main power is a a 9V 1A connected to the primary power
connector with a second 9V 1A source connected to one of the optional
power pins (7 or 8). This seems like a reasonable approach. I ran
three of the large sensors on the board with just a single 9V 1A
source with no apparent heat or performance problems. I have removed
the LEDs and switches on lines 5 and 6 and replaced them with header
pins to allow for 6 A2D lines. There are actually no servos involved
in this project. I am using the sensors and ooPIC-R for data acquisition.
