Input-only pins?

[bridger6649]

Many ESP32 related sites refer to GPIO pins 34-39 as "input-only", for example:

https://randomnerdtutorials.com/esp32-p ... nce-gpios/

GPIOs 34 to 39 are GPIs – input only pins. These pins don’t have internal
pull-up or pull-down resistors. They can’t be used as outputs, so use these
pins only as inputs:

GPIO 34
GPIO 35
GPIO 36
GPIO 39

However, the current datasheet for the ESP32-S2-WROVER indicates that those pins can be used as either input or output.

(Source: esp32-s2_datasheet_en.pdf)

Is this correct? Was there a restriction in earlier generations of the ESP32 chip?

I need to use those pins for output so hopefully the datasheet is correct!

Thanks!

Yes. The original ESP32 has these restrictions, the -S2 and later chips generally do not.
