I built an XT PCB today and forgot to check for a short between GND and 5V before powering it up. After I noticed that it wasn’t working I immediately disconnected the power and found continuity between GND and 5V on the XT board. I pulled the ICs from their sockets and then depopulated nearly the entire board (except for the push buttons) and the GND and 5V short remained until the very end, leading me to believe it was a faulty PCB to start. I got it for free – lesson learned.
What are the chances that:
I fried any of the ICs, the main CPU, or the OLED? It was only connected to power for 5-10 seconds. I’d like to know before I place a new order from Mouser.
I fried anything on the filter board that I used for power? I only had the GND and 5V connected from the filter board, not any of the other pins. The filter seems to work fine after I put it back into my regular Shruthi-1.
