Hello!
Because of several requests, the Processor Instruction Extension (PIE) chapter of ESP32-S3 Technical Reference Manual has been prioritized and now is scheduled for publishing on 8 September 2022.

Hi ALGONSI, ESP32-U4WDH chip variant installed inside ESP32-MINI-1 module has been upgraded from single to dual-core in December 2021. This information is covered in ESP32 Datasheet on page 52 in the footnote. After that date, newly manufactured ESP32-MINI-1 modules and then ESP32-DevKitM-1 boards s...

I was trying to verify the pin layout of the board but cannot find documentation. On the board itself it is marked with: ESP32-WROVER-E. The silkscreen on the board matches the pin layout here: https://docs.espressif.com/projects/esp ... vkitc.html Is the pin layouts detailed for the J1, J2, and Pi...

Hi Chevelle,

For hardware design starting with a bare SoC I suggest checking ESP32-C3 Hardware Design Guidelines.

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.
