If you look closely at this image, you will see that this is almost exactly the same as reference design layout for nRF51. So i assume that is nRF51. You can connect it to arduino, but I see very few reasons to do that...
I want to create something similar, that is why I want to connect it to an Arduino. At the moment I am using nrf24l01, but I am looking for a chip that have better range.
