I connected a Tuya mmWave Sensor (the white, thin, wall mount version) I think it is called a ZY-M100-S.
I was stupid and grabbed a non-standard micro-USB connector and it turns out +/- where reversed. Who knew that this was a thing? Anyway, the sensor lit up bright orange and the magic smoke that runs all electronic devices was released.
I'm hoping that someone with basic electronic skills can find the problem, fix it and put the device to good use.
Go to pirateship.com, buy a shipping label for 4 ounces to your address and send me the link so that I can print it.
First PM with a label gets it.
