I'm currently planing a project using the Arduino Nano ESP32.
For some buttons, I want to use the internal pull-up resistors of the chip.
According to the official docs of the ESP32-S3 all GPIOs except 34-39 support pull-up and pull-down resistors, since those pins are input only.
The pinout diagram of the Nano however shows the GPIO 38 being used for pin D11. I haven't seen any mention of that pin only being able to be used as an input, which it should be, according to the ESP docs.
Now, I'm not sure if I can or can't use the pull-up on that specific pin.
As I'm still in the planing stage, I haven't ordered the boards yet, so I can't simply try it out myself.
I would greatly appreciate it if you guys could help me out.
Edit:
So I took a look at the NORA-W106 and there it lists the GPIO38 as a General Purpose I/O pin, without any mentions of it being input only. So is the ESP32 doc wrong?
