Problem with moisture?


This is my second ESP8266 that stopped working in very short time (two-three months). I wonder if it is because of moisture? I don’t believe, that I purchased two faulty items…

Do you secure your microcomputers somehow from the moisture?

Of is there another reason?

Best regards

Have you more information.

  • Led flashing NodeMcu when reset
  • Led flashing SDS011 and is fan rotating.
  • Can you see some data on USB (with putty)
  • Can you re-flash
  • Is the NodeMcu clean or “rusty”
  • Have you change USB adapter and cable

I will try to check it today and let you know.

Thank you, my fault. I brought it home, plugged in and I see the measurements. I have to redesign powering system :slight_smile:
