Segger J-Link adapter(s) for nRF51 DK and Beacon Kit?

[Eric24]

What adapter do I need to connect a Segger J-Link module to:

1. The nRF51 DK (10028)?
2. The nRF51822-Beacon module?

The nRF51 DK has an onboard Segger JLink, so you don't need to connect one to it. If you did want to use an external JLink, one of the full-sized ones with the 20-pin .1" pitch output, like the JLink Base or the JLink EDU, you'd use the "J-Link 9-pin Cortex-M Adapter".

For the beacon module there's no header on the board. This thread devzone.nordicsemi.com/.../ recommends the 6-pin needle adaptor, or you could solder leads on and poke them into your JLink. If you think those adaptors from Segger are insanely priced .. I agree with you.

Aha, I didn't realize that it has a JLink built in! So I can run any of the Segger software? Is there any specific documentation on using it?

Thanks for the link (they aren't cheap, but in the grand scheme of things, I've paid more and gotten less).
