S3 USB Support?

Postby askpatrickw » Fri Jan 08, 2021 8:24 pm

I do not see "USB OTG interface" listed on the S3 description on the SOC page.
https://www.espressif.com/en/products/socs/

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 Not sure why the datasheet doesn't have it, it may be out of date.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.
