"Safe" GPIO pins for ESP32-S3?

[difficult-garage8985]

With previous versions of the ESP32, there have always been some GPIO pins which may briefly emit a PWM signal at boot or a logic HIGH, causing some undesirable activity in whatever the pins are connected to. There are some guides from people who tested the pins for such behavior such as this one:

The problem is that with the different pin amount and layout of the ESP32-S3, these guides are now outdated. Are there any newer references to this somewhere, or do I just need to order a devkit and test it myself? I did not find anything in the datasheet which clearly explains this.

Thanks.

Hello, have you verified those gpios? I do not see default PWM from those pins, the conclusion is so strange. We provide IO state in datasheet for your reference, generally, default value is showed as the table lists.
