I am aware of 1 iBob v1.3 that needed at new component at P3 after it and the whole board had been working for at least a while. I forget the details but I think the problem was during lab testing a scope probe fell onto P3 and caused a bad short. In anycase some event triggered the fail; it wasn't a failure on its own.
It was a bit of a hassle to remove the bad unit. I cut the old and failed P3 into parts so that each pin could be removed individually. This way I didn't over cook the rest of the board as there are lots of good connections to the heat-sinking ground and power planes in the PCB. Good luck, On Fri, 8 Jul 2011, G Jones wrote:
Hi, One of our iBOBs stopped working recently after going strong for almost 4 years. I found that the 1.5 V rail is at 0 V, implicating the TI PTH05010 regulator. Has anyone else seen one of these fail? I'm going to try swapping it for a new part to see if the iBOB comes back to life. Glenn
