Hardware Design Guidelines for ESP32-WROVER-B

[thierry37_2]

Dear Espressif team

I am developping a board based on ESP32-WROVER-B Module. I have read the ESP32 Hardware Design Guidelines, but I am not sure if some rules only apply to boards with ESP32 chip or if they also apply to boards with ESP32 Module.

Namely, it is recommanded to avoid placing any component on the bottom layer when using a 4 Layer design. In my case, this might be a bit constraining since the board contains many components apart from the ESP32-WROVER-B Module.

So, I was wondering if this rule only apply when designing a board using the ESP32 or if it also applies when designing a board with ESP32-WROVER-B Module.

many thanks for your help
