Quoted from hansj66:
I would seriously recommend people installing this anti vibration fix. A couple of days ago, node 8 on our SWLE died. One of the legs on the TO220 D9 diode had experienced som much vibration that it had broken broke off. I guess this resulted in a serious voltage spike on the input of the MP24943 regulator next to it, since the area around the VIN pin on this more or less exploded.
We are getting a new node board from Stern, but it is tempting to attempt to repair the node board by replacing the regulator ($3 on DigiKey). I guess this only makes sense if the regulator didn't let any voltage through to the output (if so, it may have fried other PCBs connected to the low voltage side of the node). Most of the components on the node board are run of the mill components, but the cortex M3 is a concern if it is damaged. Does anyone know if the firmware on this is loaded as a part of a normal software update and if it can be replaced with an unprogrammed LPC1313 ? Have anyone had any success fixing these boards ?
Are Stern actually applying this 'fix' from the factory?
From what I read it doesn't seem like it.
