https://devzone.nordicsemi.com/f/nordic-q-a/23217/programming-nrf51422-externallyI want to make a PCB with the nRF51422 chip on it. Is there a way of programming it externally using the nRF51-DK? If so, what connections do I need between the PCB and the DK?

How would I do the same with my PCB with the nRF51422 chip on it?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91318?ContentTypeID=1Mon, 03 Jul 2017 12:55:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9155536c-d39f-4073-b5bf-17140e0d2ff0J&#248;rgen Holmefjord<p>Hi,</p> <p>You can use the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/development/nrf52_dev_kit/hw_debug_out.html?cp=2_1_3_5_9">debug out port</a> (P19 or P20) on the DK to program external devices. There are many questions about this here on DevZone.
