https://devzone.nordicsemi.com/f/nordic-q-a/26150/uart-in-nrf52840i used P0.08 and P0.06 as one UART. i need to use another uart...can anyone tell me what pins other than this i can use..BTW nrf52840en-USTelligent Community 13Mon, 23 Oct 2017 06:51:36 GMThttps://devzone.nordicsemi.com/thread/103041?ContentTypeID=1Mon, 23 Oct 2017 06:51:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6d05e83b-d20b-4bab-9661-a31348d08925Jakub Rzeszutko<p>Please keep in mind nrf52840 has only 1 UART so as a second peripheral you can use UARTE.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/103042?ContentTypeID=1Sun, 22 Oct 2017 11:40:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fbdb0a10-73ec-40cc-8c47-5d519ef63b9dendnode<p>As you can read in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/chips/nrf52840_ps.html?cp=2_0_0">nRF52840 (preliminary) Product Specification</a> you can use pretty much any GPIO PIN for UART. Just make sure that your particular board (where nRF52 chip is mounted) doesn&#39;t have other components attached to that PIN (e.g. pull-ups for I2C, LEDs, buttons, NFC antenna tuning etc.)</p><div style="clear:both;"></div>
