Do you know if uFL connector versions will come from these modules as well?

I just did a pin-map of the WROVER-like module on the Devboard, and I noticed, there are a lot of NC pins on it. Interestingly, I haven't found a connection between IO26 on the DevBoard and the module it self. I wonder where is it connected to.

Hi @rudi,

Have you heard of QDR(Quad Data Rate) memory ?

From what i researched i only found with parallel address and parallel data and are very expensive(high performance too), with write and read independent interface for write and read at same time.

A "octal spi" with QDR would be very nice.

OR a quad spi(SQI) with QDR would be very nice too.

QDR use two clock signals with 90 degrees out of phase.

the mini serie contains mini-1 (PCB Ant) and mini-1U (IPEX),
also final S3 series there will been MINI module and from hearing - WROOM module -
not hearing - WROVER module -

Octal needs few pins more, yes
not sure are they outbreaked on final Modules / DevKitS - if they are used inside die for 'octal' psram.
outbreaked at the engineering wrover modul with outside octal flash and octal psram with SoC "Marlin_9_1B", yes.

BTW-FYI: Do you know the ESP32-s2 WROOM?
( FCC: 2AC7Z-ESP32S2WROOM )
it has usually ESP32-S2 and the Flash. But no PSRAM and no PSRAM inside die.
If you look into ( under the case ) you see an empty (comfortable) place for the PSRAM ( or an second flash like you want use ur code with the modul )
it comes also as an IPX version
From my knowledge - the outcomming ESP32-S3 WROOM is interesting -
it has few things combined - and mixed - Octal/Quad, inside/outside -
from hear - PCB antenna - wait for the public news - stay tune


edit: typos, S2 IPX edition added

yes, example

Well, I'm glad me and my company signed an NDA with Espressif, so I can get my hands on stuff when available. Perhaps I need to wait for my WROOM samples to arrive and docs to be more and more completed

I agree. Excitement intesifies!

I just wonder if Espressif plans some RISC-V boards with more than 1 core and 64bit since it is very cheap and super low power consuming design. Perfect for 5Ghz and HD vid stuff

I think, 64bit will almost never come. It is a bit overkill, since the memory and storage ESP MCU-s have to address will never be more than what is possible with 32bits.
More than 1core is possible though. I think ESP32-C3 is a good platform to test RiscV capability. I think more cores could come in the next chip.
We'll see.

Why 64bit is overkill? It is faster from execution point of view and it can handle 2x more bits parallel in one cpu clock cycle .
I tested K210 and this monster running at 600Mhz with camera 640x480 plus LCD 480 with full face recognition takes at peak 0.7W of power for all devices and when idle it goes below 0.05W. That's two core 64bit risc-v. Risc-v has instruction compression saving ram space and can even perform 128bit operations. This is the future
