Also should mention that AnalogLamb are working on a drop-in replacement for the WROOM-32 module that we use, but with the 32Mbit PSRAM inside. Pinout is the same. Still waiting for details on this (especially whether it uses 3.3V or 1.8V for flash and SPRAM).

I just don’t think we need to wait for these. At some point, it is ‘good enough’, and the ESP32 WROOM-32 seems fine for our purposes today.

Regards, Mark.

Probably another few months before code support for that stabilises, and modules available in quantity. Perhaps in our future we could switch to that, but for the moment I think we’re ok. Just need to be careful.
