How can I connect a led to nrf51822?

[efka]

Hi there,

I want to program nrf51822 without  nRFgo starter kit. 

Which pins I should use?

Why do you want to start with this old product?

Note that the nRF51 series is not recommended for new BLE designs:

But the nRF51 DK is still available:

Better still would be to start up-to-date with the nRF52832-DK - then you get a free licence for Segger Embedded Studio for your development, programming, and debugging:

(Other IDEs are available)
