Robin,

Thank you for the info and the link - I hadn’t realized that the EDA files were 
available publicly.

I have been using a B210 board for about a week now to run OpenBTS and 
OpenBTS-UMTS.  I left the board powered on in its enclosure overnight, and when 
I arrived in the morning discovered it not working, the power led flickering, 
and my computer alerting that there was a USB power surge.  I took the board 
out of its enclosure and discovered capacitor C674 had completely burned up.

Has anyone else encountered a hardware failure as catastrophic as this with the 
power supply?

Does anyone know the specs on that capacitor (capacitance, voltage rating, 
etc.) so I can possibly replace it on the board myself?

I'm using Rev 4 of the B210, and I have a GPSDO-TCXO module installed.  I was 
using a 9V, 1.5A wall wart as the power supply and had the USB3 cable connected 
to my PC.

Thanks,
Billy
