differences between the nRF52-DK and the Preview DK?

[Nitram]

Hello!

What are the differences between the nRF52-DK and the Preview DK? I have heard that there is an error with the RAM: devzone.nordicsemi.com/.../

Are there any more problems with the Preview DK?

Thanks!

Hi,

The preview kit, was just that, a preview. It had an early, un-complete nRF52 mounted. Have a look at the nRF52832 IC revisions compatibility with development HW to find kit revisions with associated SoCs. Then refer the SoC revisions and look at the Errata to find what features are missing or not functioning properly.
