I missed the key difference. WROOM-2-N16R8V has octal flash and WROOM-1U-N16R8 has quad flash. Sorry for that. ESP32-S3-WROOM-2 modules have octal flash and PSRAM. ESP32-S3-WROOM-2_Ordering.png By comparison, ESP32-S3-WROOM-1 modules have quad flash and either quad or octal PSRAM. ESP32-S3-WROOM-1_O...

Hi Demirug, The short answer is that dedicated GPIO feature is supported for ESP32-S3. For ESP32-S2 there are two methods to operate dedicated GPIO: by accessing registers and by using specialized CPU instructions. In newer chips (e.g. ESP32-S3 or ESP32-C3) the first method has been been removed and...

Hi villagri,
We do not have other ESP32-S3 publicly available documents with more information on AC characteristics.

Hi andylinpersonal,
The other difference is that ESP32-S3-WROOM-2 modules have a newer a version of ESP32-S3 chip inside.

More on VSPI or HSPI usage for PSRAM running at 80 MHz is in CONFIG_SPIRAM_SPEED.

I am sorry for the errors in the product selector. This has been corrected.

Both SPI0 and SPI1 are used for in-package flash and PSRAM of ESP32-PICO-V3-02.
SPI2 (HSPI) and SPI3 (VSPI) are free to use.

Is there a way to tell from part numbers or suppliers which chip revision I'm ordering before I order it? Expanding on ESP_Sprite's reply: ESP32-PICO-D4 is a chip with V1 silicon. ESP32-PICO-V3 denotes chips with V3 silicon. Currently there are two options of ESP-PICO chip with V3 silicon: ESP32-PI...

Hi silverj,

Notifications are down to the chip series, not for individual documents, though.

Hi chrismerck,
The equivalent of ESP32-WROVER are ESP32-S3-WROOM-1 and ESP32-S3-WROOM-2 variants with PSRAM.
These variants provide a wide range of flash and PSRAM sizes. Therefore there will be no ESP32-S3-WROVER.
