On page 3 of the esp32-wroom datasheet (PDF) it shows a series of pins with type "I".
What does pin type I mean? Are these different to the pin type I/O pins? If so, how?

Some pins can be input and output: I/O (or sometimes General Purpose I/O: GPIO).
Some pins can be outputs only: O.
Some pins can be inputs only: I.
Some pins can be power: P (note that some datasheets will differentiate between input power and ground).
And some pins can be not connected: NC.
