ESP32 Forum

Hi Everyone,

i would like to ask you which is the difference between the WROVER-B and WROVER esp32 module.
In the appliacation where i use the ESP32, unfortunatly the operative temperature ranges changes from 60 to 75 °C, looking to the WROVER-B datasheet i have a operative temperature range form -40 to 65°C but in the WROVER datasheet i see -40 to 85°C.
My question now is... why there is 2 different temperatures? only because the WROVER -B could be built with a 16MB PSRAM?
Which are the effects if i use the WROVER-B at 75°C? there any effects on the life time cycle? anyone of you have experience using the ESP32 in application where the temperatures are high?

Thanks to everyone in advance!

Wrover-b uses 3.3v flash and ram. Wrover uses 1.8v. contact sales about industrial temp version.

Thank you very much! i need to use the wrover-B since i have 3.3v.
Last question, does exist the version with higher temperatures? i saw in other datasheets, like the WROOM, that the chip could be provided with 105°C temperatures, i didn't find that info on the WROVER-B datasheet that's why i'm not sure if that version exist.
Anyway i'll ask to my contact sales also.

Thanks again!

Wrover still uses 3.3v supply and gpio
