WROOM Recommended Footprint

Postby dotthree » Tue Mar 14, 2017 6:02 pm

Hi,

I can't seem to find any documentation in the official documents and datasheets for what the recommended PCB footprint should be for the ESP-WROOM-32. Could someone point me in the right direction?

You can find the below footprint dimensions on the hardware design guidelines pdf from the following link https://espressif.com/sites/default/files/documentation/esp32_hardware_design_guidelines_en.pdf

aaquilina,

That is the dimensions of the contacts on the wroom module but not a specific recommendation for the dimensions of PCB footprint. I would really like to know the dimensions of the wroom footprint on the esp32-devkitc is for example as that seems to work well.

I think Gerbers are available in reference designs on http://espressif.com/en/support/download/overview
