Default (MUX) pins for uart1 are used by flash. This doesn't matter IF you know about gpio matrix.

No you can assign it to other pins using gpio matrix

Re: ESP-WROOM-32 production capacity

I think it is typically 1wk lead time on orders <10k but ask sales@espressif.com

Re: ESP32 PSRAM support

OK thanks for clarifying. Any info on rev1+SPIRAM hardware and toolchain in unit testing and CI flow?

Would be nice to have firmware ready for production when wrover ships.

Would also be really nice to know when to expect S0WD, 8689, and the new chip.

Re: Deep sleep wake-up triggered by low to high logic level of GPIO

You could use a hardware timer or edge detector circuit to do this or use a ULP program to wait before enabling ext0 wakeup or use 2 separate deep sleep paths one is a 40s timer deepsleep which ends in a wake stub to enable ext0 deepsleep.

Re: ESP32 PSRAM support

If any, post 2.1. Ok so how to look at esp32 rev1 SPIRAM support in IDF from a product planning standpoint? Will it always be second class citizen in terms of IDF updates, separate branch? Do you suggest to consider waiting for "ESP-NEXT" chip for fixed SPIRAM and first class IDF support?
