We will be back to full staff on January 3rd. Happy holidays and happy new year!</p> <p>There shouldn&#39;t be an issue using an nRF51 DK (pca10028) to program an nRF52 board. Have you checked out the debug output section in the <a href="https://infocenter.nordicsemi.com/pdf/nRF51_Development_Kit_User_Guide_v1.2.pdf">nRF51 DK user guide</a>?</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
