Where can I access the full spec sheet

[Dan Colob]

The site is just showing a product brief PDF, where can I access the full datasheet? Is the crystal oscillator on board or an external connection is required?

Hi,

You can find the product specification on our infocenter here: nRF52833 Product Specification. You need to have an accurate external 32 MHz crystal to operate the RADIO peripheral while it is optional to have a crystal for the low-frequency clock source.
