Have you seen https://docs.espressif.com/projects/esp ... r-kit.html and followed the link in your post? Do you see a USB port when you plug it in and are there any lights or indications the MAC sees the board?

Hi Franklin, thank you for your response.

No, there is no indication from mac that it recognizes the board.

The base issue here is the lack of a new COM port showing up when the Wrover Kit is attached via USB. The existing COM port options are apparently other devices.

Verify the USB cable is good by using it with some other device and verify it can transfer data and is not a charge only USB cable.

I am able to exchange data on another device using the same cable.

OK, thanks for checking the USB cable. Not sure what's going on here, but can try a replacement.

Send an email to [email protected] with a link to this thread and your order number and they can send you a replacement Wrover Kit.
