SDK of NRF51822 free of charge?

[sansil]

Hi

I'm starting with NRF51822. I'm going to develop a costum PCB using this chip. I'm a bit confused because searching on the forum I saw that I need a product key to use the SDK and other software? This is correct?

Thank you, Regards Santiago

You don't need product key anymore to access SDK, it is available at:

developer.nordicsemi.com
