https://devzone.nordicsemi.com/f/nordic-q-a/8408/nrf51-dk-uart-connectingHello, I want to using nrf51 dk with uart communication. So, I want to know how connect both PC and nRF51 DK. I&#39;ve download with 5pin connector to USB. In former days, I did a UART communication using Arduino with 5pin connector. This case, it wasen-USTelligent Community 13Wed, 29 Jul 2015 07:28:41 GMThttps://devzone.nordicsemi.com/thread/30547?ContentTypeID=1Wed, 29 Jul 2015 07:28:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c7987ec2-3e52-4023-8fbe-6ead7dde88ae&#216;yvind Karlsen<p>Please see <a href="https://devzone.nordicsemi.com/tutorials/4/testing-and-using-a-simple-ble-application/">this tutorial</a>, a part of it is connecting to your kit via UART.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30546?ContentTypeID=1Wed, 29 Jul 2015 07:18:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa93789f-6044-4398-993a-8ef915cd4d83nknaaa<p>Thank you for your answer. So, can I communicate UART with just using one connector that can download firmware?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30545?ContentTypeID=1Tue, 28 Jul 2015 05:06:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:27e8446e-8ee0-4185-9e86-fa9b56872ae7RK<p>The UART on the DK is connected up so it appears (if you use the pins listed in the manual) as a USB serial device on the USB connector on the board.
