Excuse if this is a duplicate message. I don't know if the first one went through.
I have a RPi3 in a node that stopped working. With testing I determined that the RPi 3.3 V is bad, it is only 1.25 V at test point 8. The 5 V is ok and the 1.8 V is ok. I tested this with nothing connected and the SD card removed. This board is only a few months old. Has anyone experienced a failure on the 3.3 V and have any idea what could have caused it?
In this node I am using the DMK URi and a FT-7900 radio.
Can something in the USB interface have caused this? Can a corrupted SW in the SD card could have caused this? I have ordered a new board but would like to try and understand why it failed before I install a new board and potentially fry it since I don't know why this one failed. It could be just a random failure?????
Thanks, Chris - W6CS - 73
