Heat problem
Hello,
I put a small breadboard on a super carrier board to do some experimenting. On the breadboard I have a uM-fpu, a compass module and a gps module all hooked up to the stamp. I connected some long wires from the board to the gps module so I could put it next to a window where it receives a signal.
The problem I have is that the heat sink on the board gets very hot and on a few occasions the board has turned off. Is this due to just overloading the board or are the long wires to the GPS module causing it?
Also' will this damage the stamp?
Thanks,
Mike

1) Your power supply could be relatively high. Anything greater than about 5V is just turned into heat (power as heat = voltage above 5V x current drawn). The regulator does require at least 5.5 to 6V to regulate properly.
2) Your breadboard could be drawing too much current. GPS modules tend to be relatively power hungry or you may have a short on your breadboard.
3) If the regulator (and board) is in sunlight, that will increase the operating temperature which will worsen the problem somewhat.
The Stamp should be ok unless there's something wrong with the wiring and there's a short circuit somewhere. Even then, it's pretty robust. Stamps tend to be damaged by connecting the power source backwards or by connecting the regulated power input to something over 5V.
I'd think that if you are, then a short circuit is quite unlikely. But if the circuit is not working, I'd think a short circuit would be easily the most likely culprit, right?
The wires I am connecting the GPS with·are about 5' long and I am using the parallax 12v power supply.
Thanks,
Mike
