ESP32 Forum

I do not see "USB OTG interface" listed on the S3 description on the SOC page.

Is this just an omission in these early docs or will it really not be supported?

Thanks!

hey dude!
I have looked a bit further into this and found this:
https://www.cnx-software.com/2020/12/20 ... 266-price/
searched with: ESP32-C3 Series USB support

On that picture it says it would support USB BUT, when I looked in the datasheet: https://www.espressif.com/sites/default ... eet_en.pdf
I didn't find any info about USB so the way I see it. It probably DOESN'T support "USB OTG interface"

I'm not an expert in this just another hobbyist doing it for the fun.

As far as I know, the S3 will have USB OTG support (both low-speed and high-speed, same as the -S2). Not sure why the datasheet doesn't have it, it may be out of date.

The ESP32-S3 and ESP32-C3 are different products, so USB not being listed in the C3 datasheet does not say anything about the S3.

I do not yet see any ESP32-S3 datasheet, but the graphic on the Espressif press release does show USB OTG under the peripherals.

For completion: there is no USB OTG on the -C3. There may or may not be some other (more limited) USB functionality, but that depends on if we can make it work in silicon.
