DUET2 WiFi is not responding, 3.3V LED is OFF, so I followed instructions here and replaced the 3.3V voltage regulator for a new one. However the problem persisted. I removed the regulator and measured it outside and it got damaged, I measure 5.0V at Vout. Could it be a short between 3.3V and ground? What do you suggest checking?
