What is the ESP32-WROVER-B?

Postby mitchk » Wed May 23, 2018 4:59 pm

I see the ESP32-WROVER-B part listed on the Espressif documentation page (https://www.espressif.com/en/support/download/documents) but it does not bring up any documents and I couldn't find anything about it searching online. I am starting a new design around the ESP32-WROVER so I am curious if this new part has any new features that would be useful and if it will be a drop in replacement for the ESP32-WROVER. Thanks.

It is probably the second gen version of wrover like the wroom-32d/u so it should have improved rf and more certifications.

Found this,
https://www.espressif.com/en/media_over ... 2-wrover-b
https://www.espressif.com/sites/default ... eet_en.pdf

Seems like the main thing is 8MB sram instead of 4MB, unsure how to use the extra 4MB since the ESP cannot map that additional ram to address space? The flash and sram now runs at 3.3v instead of 1.8v.

Wounder if the Flash and SRAM signal integrity issues have been resolved to make it possible to use the 80MHz SPI rate?
