https://devzone.nordicsemi.com/f/nordic-q-a/90016/pin-assignments-in-nrf52840dk-boardHello every one Pin numbers on DK boards are printed as P0.08 or P1.20 etc. but in nrf_config.h files Nordic assigns numbers to the pins. There are pin numbers from 0 to 47 but I can not figure this out and find a relation between numbers 0 - 47 anden-USTelligent Community 13Fri, 15 Jul 2022 12:24:47 GMThttps://devzone.nordicsemi.com/thread/377195?ContentTypeID=1Fri, 15 Jul 2022 12:24:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4123a8ef-94f0-4ad6-9495-4bdd8fff0508Jared<p>Hi,</p> <p>There are 48 GPIO pins on the nRF52840. The GPIO pins are divided into Port 0 and Port 1, where GPIO pin 0-31 is apart of port 0, and GPIO pin 33-48 is part of Port 1. The numbering restarts from 0 after 32, but with Port 1. For example&nbsp;<span>P1.04&nbsp;is GPIO at Port 1, Pin 4 which is equal to GPIO pin 36.&nbsp;</span></p> <p><span>See the<a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/gpio.html?cp=4_0_0_5_8_1#topic"> GPIO chapter</a> in the PS.</span></p> <p><span>regards</span></p> <p><span>Jared&nbsp;</span></p><div style="clear:both;"></div>
