Please take a look at ESP32-S3-Zero does not work on PlatformIO - #10 by sivar2311
I also created a esp32-s3-fh4r2.json - see 2 posts later.
I would be pleased if you could test this.
Oh, the ESP32 are very well documented by Espressif!
Maybe you missed the datasheet?
The problem is rather that there are now many different modules and they have to be configured accordingly - which is the tricky part.
