Have a ESP8266 (D1 Mini NodeMCU), can't find COM port

Just purchased a ESP8266 board (WeMos) and am trying to set it up.

I have installed the Board with Board Manager, but I can't get the wired COM port to populate under Tools so I can upload a sketch.

Also installed the CH340G driver, but still can't get it to work.
I am using a Mac with iOS High Sierra.

Any suggestions?


Make sure your USB cable is fully inserted into the Arduino board and the computer.

You may be using a charge-only or defective USB cable. Try a different cable or test your cable on another device to confirm that it works for data.

Ahh good point. I'll give it a go this evening.


Yup! that worked.

Was using the wrong USB cable.

thanks !

You're welcome. I'm glad to hear it's working now. Enjoy!
