Hi,
Would it be possible to adjust the ESP32-EVB to include a WROVER module? I'm interested in the higher PSRAM capacity found in the WROVER module.
Thank you,
Bogdan
It is not possible, it would require full re-route. The reason is visible here:

Thank you for your fast reply.
I knew that a direct replacement wouldn't be possible. I was thinking either about a new product, or by modifying the current board to use an adapter from wrover to wroom.
I would expect the adapter to have at least the same length as the esp wrover module, and the ethernet interface would not fall well in the design. But I guess the board could be made longer and the ethernet interface could be moved at the edge of the new board, such that the routing modifications would be minimal.
We have a boards with WROVER option like ESP32-WROVER-DevKit-Lipo:

Also the ESP32-ADF: https://www.olimex.com/Products/IoT/ESP32/ESP32-ADF/open-source-hardware
Placing WROVER is not possible for ESP32-EVB since the board uses too many GPIOs and has too many peripherals and the WROVER has less GPIOs available (they are used for the internal SRAM).
