Some boards with 16MB Flash:

ESP32-OLED-V2-0-TTGO
M5Stack Fire
Wemod D1 Mini Pro
Widora Air 16M

Being on a topic of esp modules - is there a reference design for dev wrover board with built in usb/ttl?

ESP-WROVER-KIT V3
ESP-WROVER-KIT schematic

Awesome!!!
Thanks.
That's what I missed on their website.

I must mention - recently I bought Esp32 Wroom 16Mb flash and it is recognized properly without any issues.
Actually I noticed quite speed increase in flashing time.
With such nice built in flash size I would like to install some nice web server and test how it performs on that board.
Not sure how good is the server from the idf examples

I have been searching all over and I can't find any dev kit that has 16MB flash size or even 8MB for that matter.
I want to develop an application that needs to update OTA and the 1MB partition is too small.
Is my solution right now only custom design from scratch??

Hi, I am working on a new dev module that will have 16MB Flash and 8MB PSRAM. I just got the final parts to get the prototypes built and should get them sent off for production next week (I am moving house at the moment so not much is happening now).

Its also got a SAML21 co-processor which handles the USB port and bootloader, and can also be programmed for more IO resources, better A2D, etc. The module also has an optional on-board microSD card (4 bit mode) if you need more storage, or it can be reduced to 1 bit mode, or disabled all together if you need more IO. Plus Lithium ION battery connector and charger.

Has anyone gotten the 16mb flash to work with the Arduino IDE? What is the procedure?
