Short Circuit SDR - Now Fixed
My SDR stopped working sometime last night. I've unplugged it from the BeagleboneAI and done a little checking. The 5VE is s/c. The 5V is fine. I've also checked across the caps of the 1V, 1.8V and 3.3V. all seem high resistance so it's pretty certain not the BGA that's s/c. What does the 5vE feed? I've looked at the cct diagrams and cannot see what the 5vE feeds other than out to the BB pins (it's unplugged from the BB). There are a couple of caps either side of the T301 which all of course are essentially in parallel. They all read s/c, So, question is, what does the 5vE feed on the kiwi board other than out to the BB? Or is it one of those 4 caps that have gone s/c?
Any help gratefully received. And I'd got it all working so well with the BBAI and a temp of between 45 and 48C
