Using ESP32-WROOM-32 or ESP-WROOM-32D

Postby plajjd » Wed Nov 28, 2018 4:39 pm

Can someone from Espressif provide recommendation as to the differences between the ESP32-WROOM-32 and 32D parts?

We are preparing to order production volumes, and it is not clear to me what the differences are.

We have been using the ESP32-WROOM-32 for development. But I see that the 32D is a newer part, I just do not know what the advantages of the 32D may be.

Thank you!

Phil.

Hello Phil, the D version is the updated module and recommended for new designs in Espressif Product Ordering Guide, it uses the 5x5mm ESP32 package inside, that allows a different internal routing than the non-D. The antenna design has also changed. The result is better RF performance. If you can switch to the D, you may want to do so, otherwise you can go on with the non-D. From a fw standpoint it does not make any difference. But looking at scalability, the 8M, 16M and U versions are all derivatives of the D. Thank you for using Espressif.

Would you please confirm these modules are fully pin-to-pin HW compatible and interchangeable. I mean that I have HW design which has been already produced once in mass production with ESP32-WROOM-32. And now I need to repeat the production - can I use ESP32-WROOM-32D instead of ESP32-WROOM-32 without any change in production process (Schematics, Layout, Flashing, FW)?
