https://devzone.nordicsemi.com/f/nordic-q-a/5041/programming-3rd-party-modules---general-workflowDear Forum, I just unwrapped my new nRF51 DK board and already played with some mbed example programs which worked beautifully! So first of all - thank you Nordic &amp; mbed team for making this so easy! The next question which comes up of course is en-USTelligent Community 13Fri, 16 Jan 2015 09:10:52 GMThttps://devzone.nordicsemi.com/thread/17763?ContentTypeID=1Fri, 16 Jan 2015 09:10:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1e5fb15-2db4-452f-85c8-7d233b6b42c2glycylalanin<p>Dear Stian, thank you very much for your help. This was desperately waiting for!

This is for programming the beacon kit with a dedicated programmer, but the pinout is the same for the Debug out port on the nRF51 DK. You should have a look at the <strong>PCA10028_Schematic_And_PCB.pdf</strong> on page 4, located in <a href="https://www.nordicsemi.com/eng/nordic/Products/nRF51-DK/nRF51-DK-HW/38675">this zip-file</a>, for the complete pinout specification. So you should be able to just solder a few wires on to the ISP130301 in order to program it. Go to the ISP130301 datasheet to find the pin configuration for that module.</p> <p>You do not have to disconnect the on-board nRF51422 on order to activate the Debug out port. It will detect the supply voltage of the external module and switch to that target. See the <a href="https://www.nordicsemi.com/eng/nordic/Products/nRF51-DK/nRF51-DK-UG/38677">nRF51 DK user guide</a> section 5.10</p><div style="clear:both;"></div>
