[Eric24]

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

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

Hi

Here is a short blog post on how to program the Beacon using the nRF51 DK: Programming the nRF51822 Beacon Kit with the nRF51DK. It has a suggestion for a needle adapter as well.

Here is a relevant thread on devzone: Recommendation for debug connector for nrf52 product.
