Hi rudi,

You don't miss much, do you?

Announcement for revision 2 should be coming soon but I don't think any information has been released yet. No huge changes.

Revision 3 is a placeholder for now.

hi Angus, the new hw things (CHIP7 2-2-A, ESP32-S2, ESP32-S2 Beta-DevKitC V1.1, ESP32S2, ... ESP64)
not that you can still believe I already have this
No, unfortunately not - espressif makes me squirm right this time
I see these posted here and there and pick the cherries infos, but I could not test it myself yet.
my eyes are alert ))

thanks for the information
best wishes

Hi all,
somehow I cannot find this "announcement for ESP32 rev 2". As I noticed these days that I can communicate with 20kbaud CAN bus only from rev 2 upwards I am really interested to get my hands on rev 2.

BTW: I cannot find any trace of a CAN register description in the technical reference material for ESP32 - is there a reason for this?

Thanks,
Thomas

Rev 2 is pretty much a revision that is produced in small numbers and in all likelihood won't be widely available. Suggest you wait for rev 3, which will (probably, as usual this is no guarantee) come out in q1 2020 and will be available from the usual sources. (And yes, rev 3 will include all the fixes rev 2 has.)
