On-Board LED on the Wrover-B ?

Postby GeorgeFlorian1 » Tue Apr 16, 2019 11:30 am

Hello !

Short Story:
The Wroom-32 DevKitV1 has a LED assigned to GPIO 2.

What is the GPIO for the on-board LED on a Wrover-B ? It doesn't seem to have one, though.

Long Story:
I got to play around with a Wrover-B DevKitV4 and I don't find any documentation on it. The documentation I found showcased different pictures of the Wrover. Mine looks different.

This is what I have: https://i.postimg.cc/LsxKbjWC/20190405-135731-1.jpg
This is the documentation: https://www.espressif.com/sites/default ... eet_en.pdf

This is what's in EVERY documentation: https://www.espressif.com/sites/default ... B.001.jpeg

You see that they have a couple of pins that are different ? And they look very different ?
But that's beside the point.

They look the same to me.

You can read about the board you have here:

It doesn't appear to have an LED other than the power indicator.
