ESP-WROOM-32 vs. ESP-WROOM-32D

[_scrat]

Hi,

I wonder about the differences between ESP-WROOM-32 and ESP-WROOM-32D. As I can see from the Espressif website both modules have the same pins the same amount of memory. The only points seem to be that the 32D is 0.3mm thicker and the esp32 chip integrated in the module has a different package. But what is the substantial difference? Which module should I use for a new design?

Regards,

Michael

Rf performance may be improved, 32d should definitely be rev1. 32D is newer so it would be disappointing if it wasn't at least slightly improved.

@WiFive We switch from ESP-WROOM-32 to ESP-WROOM-32D. We can't flash even the helloworld. What's wrong with switching to ESP-WROOM-32D?
