I recently lost a power module after I plugged in an XBee module. I’m running the following modules:
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?
