Hello everybody,
Is there any way to use the ESP32 WROOM as a USB keyboard?

Detail has to be through USB, through bluetooth I can already do it, but some old computers do not have this feature.
I found a solution for the ESP32 S2/S3 but for the ESP32 WROOM i didn't find anything that works.

Thanks for the help.

The ESP32 WROOM from Espressif doesn't have an USB interface so how did you thought to realize that? Do you have another board but forgot the link to it?

Thanks for your attention friend, I'm just looking for an alternative without having to change the ESP32 wroom, but I didn't find any simple and cheap alternative.

For now, I suggested to the customer to use a usb/bluetooth adapter, but if possible, I wanted to eliminate the bluetooth transmission and send it only through the usb keyboard.
any suggestion?
Tks.

Given only the information in your post I would recommend to use another board, probably an Arduino Pro Micro. That one has an USB interface and the Arduino IDE has the necessary libraries to send USB keystrokes.

Unfortunately I cannot replace the ESP32 WROOM, as I use WIFI together with the ESPNOW protocol.
Needed a solution that worked together with WROOM.
TKS.

Combine a Pro Micro with the ESP32. The ESP32 cannot be used as a USB keyboard.
