I’m curious if anyone else has encountered this? According to the documentation and schematics, the LimeSDR-USB should accept a 6-12V DC barrel plug (center-positive). However, when I plugged in a 12V DC adapter to my board, it immediately died and will no longer power up, either from DC or USB. No LEDs, no USB enumeration (dmesg / lsusb). It’s dead.
Are there known issues and/or fragile components that could help me narrow down the culprit?
