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
