ESP32 Forum

I have noticed a discrepancy on the current ESP32-WROVER/ESP32-WROVER-I Datasheet (v1.5).

The latest data sheet shows 3 NC pins for the Wrover Module. Pin 27,28 & 32 on page 8 (Pin Layout).
Yet, the pin description on page 9 ,shows Pin 27 as IO16, and for Pin28 as IO17. Which is correct ?

I am reading the latest ESP32-WROVER/ESP32-WROVER-I Datasheet here.

NC is correct

How do you know this?

Because io16&io17 are used internally for psram and the table was just lazily copied from wroom32 datasheet

FYI, WiFive is correct (although I wouldn't use the word 'lazy'... our doc team in general is quite hardworking.) I'll give the docs team a headsup that this is in there.
