https://devzone.nordicsemi.com/f/nordic-q-a/110440/i2c-pinsHi, I just started exploring Nordic chips to learn about it. I need help to understand how it&#39;s GPIO works for various funtions. For example, I2C line is some dedicated pins or I can use any pin then manipulate in software development Same for other functionsen-USTelligent Community 13Mon, 22 Apr 2024 15:10:49 GMThttps://devzone.nordicsemi.com/thread/480042?ContentTypeID=1Mon, 22 Apr 2024 15:10:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f3727048-deb5-4543-9265-a700f094b05dalleekhaan<p>Thanks <a href="https://devzone.nordicsemi.com/members/naeem-maroof">Naeem Maroof</a>&nbsp;<br />I will check course as well</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/480031?ContentTypeID=1Mon, 22 Apr 2024 14:11:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:628e7eed-e4f8-4f62-82ce-5dea47d0b9acNaeem Maroof<p>Hi,</p> <p>You can use any of the available pins for using with I2C etc.</p> <p>May I suggest you go through our <a href="https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/">Dev-Academy course</a> that introduces with the Nordic Connect SDK, Zephyr RTOS, and has exercises that use the peripherals on the SoC. You will see that we can use different pins that could be defined in overlay files. Lesson 5 and 6 are specifically about UART and I2C.</p><div style="clear:both;"></div>
