Hi There, I have been working on a project using a beaglebone black which I am trying to power with a 3-cell LiPo battery. To do this, I have connected the output of a hobbywing ubec 5V-3A voltage regulator to pins P9_5 and 6. This seemed to work well for a while, but just now the BBB abruptly turned off and will not turn back on. I have tried disconnecting everything from the BBB and connecting it to my PC with the USB cable. This results in a quick, faint flash of the PWR led followed by nothing. Pressing the power button with the USB cable plugged in yields the same behavior. I just tested the voltage regulator output and my voltmeter reads 5.3 V. My understanding is that the BBB requires a well regulated 5 +- 0.25 V power input. So technically my power supply is 50 mV above the limit. Is it possible that I have fried the board by doing this? Is there any way to recover it without buying a whole new BBB? Thanks in advance for your help!
