Need help to get default state of unused IO pads for ESP32 modules

[Ritesh]

Hi Espressif Systems Developer,

We have started to use ESP32 SoC as well as ESP32 based modules into different product which are running successfully.

Now, I have one question like what is the default state of unused GPIO or IO pads into module itself?

Let's take one example like there is one IO3 which I haven't used into my product then what will be the default state means HIGH or LOW and input or output direction.

So, I just want to get I formation regard that so that I need to configure it from software side if state is tristate or not fixed

Look at datasheet appendix A you can see that io3 has input mode with weak pull-up and default function is u0rxd
