Hi all,
I'm want to connect ESP32-PICO-D4 to 1.8V peripheral but I'm a bit confused.
Is it possible to provide 3.3V only for VDDA and VDDA3P3 and 1.8V to VDD3P3_CPU so that GPIO's be 1.8V ?

Re: ESP32-PICO-D4 and 1.8V
I see nothing in the datasheet that prohibits this, although keep in mind that this is not a common configuration (as in: I have never seen someone else try this before) and it only gives you 5 GPIOs running at that voltage.

Yes, that's what I thought. Thanks for confirming.
Since I'll be the first who's trying will update here about results
The GPIOs that you mentioned are 5, 18, 21, 22 and 23. Right?

There's a few more IOs under that power domain... I see 1, 3, 5, 18, 19, 21, 22 and 23 here. (1 and 3 are TxD0 and RxD0, respectively.)
