I recently lost a power module after I plugged in an XBee module. I’m running the following modules:
Spider
JD11d
Micro SD
IR
T35
RS232
I added up all the load for these and it about 361 mA.
I have been running in this configuration for months. Then plugged in an XBee module and the Power module died.
The XBee is rated at 40 mA so the total load is around 400 mA which is about 50% of the rated DP Module.
With the new DP Module it works fine but I noticed the 3.3 regulator runs very hot.
My question is has anyone install any heat sinks on the regulator?
Could be but its working fine with the new power module. The regular runs hot even without the XBee plugged in. I just don’t like chips running that hot and though about putting a heat sink on it.
There really is no way for me to think to test the temp unless you had an inferred thermometer or some kind of thermometer that you can place on the chip and read it.
