Why no easily available design data for the nRF52805? I could not find a datasheet (like most other manufacturers) that gives any packaging information or PCB footprints.

I need  a full datasheet for the nRF52805 device - I could not find the information on the website, which is visually impressive but technically very unclear in my opinion.  Information is very hard to find and not logicically organised.

Hello,

As @Dmitry said, I too would recommend taking a look at the nRF52805's infocenter page.
Furthermore, if you are interested in developing for the nRF52805 using the SDK and an nRF52 DK ( emulating the nRF52805 ) then this blogpost might be beneficial to have a look at.

Please let me know if anything should still be unclear.

Best regards,
Karl
