@teastain2 the v2.3.1 version does have a CP2104, but the label on this board is clearly a v2.3.2.
When I plug the cable straight into the board, Windows doesn't show anything - no COM port or anything else. Device manager doesn't blink at all. The board just powers on.
I'll try to get in contact with LilyGo later today...
I was planning on uploading a sketch fron the Arduino IDE but PlatformIO is also installed and ready to go.
And I'd be surprised if my supplier is mistaken.. I had email contact with them about the board and they specifically indicated this difference between the two versions, as I asked them because there's no information online.
