Looks correct per schematics. Did not test beyond that.

@dhalbert just to verify - the changes to mpconfigboard.mk and sdkconfig are intentional as well?

Yes, they are intentional, to make the boards match. They are not important. I was just doing a directory compare and noticed the differences.

These build errors are new and unrelated to the changes :(

Tested on Feather Reverse TFT ESP32-S2 and ESP32-S3 using by doing a UART loopback and writing and reading bytes.

Just pasting this here to document the general behavior the bug created:

The build error is something upstream: esptool.py v5.0.2 (first 5.x.x release) was two days ago. Other people seeing the same problem:
espressif/esptool#1107

ModuleNotFoundError: No module named 'esptool.__init__'; 'esptool' is not a package

So I'll wait a bit before re-running this.

espressif/esptool#1107 was fixed, and a re-run was successful.
