Well, the resistor is 39 Ohm. I guess this is acting as a fuse and something else is also broken. I already destroyed one failed SonOff mini where this component had become open circuit because I didn't investigate to carefully.
I've had two devices fail now, after only a couple of days use.
Hi, I connect in the wrong way my sonoff mini, nobody solve replacing the 39 Ohm resitor (R9)?
Please let me good news.
