Re: Need 16 MB Flash supported ESP32-WROVER module

We need at least 10000 if they are ready to make ESP32-WROVER module with 16 MB internal flash memory. I thought for 10,000 quantity, Espressif would do it? MOQ 10 reels, @650pc a reel, is 6,500 modules. https://www.espressif.com/sites/default/files/documentation/espressif_products_ordering_informa...

Re: Need 16 MB Flash supported ESP32-WROVER module

Some distributors are carrying 8m and 16m wroom32 now so maybe they will have wrover too. I think maybe the design is being updated and more certs added? Do you have contact of trusted distributers who can help us to make custom ESP32-WROVER modul with 16 MB as internal flash memory instead of 4 MB?

ESP_Angus wrote:Hi Ritesh,

There are no changes in the ESP32 silicon between the modules you mention. All will have ESP32 revision 1 silicon. The differences are the ones you mention (with/without PSRAM, antenna layout, module form factor and pinout).

Ok.
