https://devzone.nordicsemi.com/f/nordic-q-a/80554/nrf-sdk-nrf51822Hi, I am new and just starting out. I am using a nRF51822. I downloaded SEGGER and the nRF sdk (nRF5_SDK_17.1.0_ddde560), but I can not find nRF51822 in the config folder. Is there somewhere I can download them?en-USTelligent Community 13Tue, 12 Oct 2021 11:51:17 GMThttps://devzone.nordicsemi.com/thread/333721?ContentTypeID=1Tue, 12 Oct 2021 11:51:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2e724f03-c09d-4c87-8ae7-84f6ce3476c1Priyanka<p>Hi,</p> <p>The nRF51822 is a previous SoC and it is not compatible with the&nbsp;<span>nRF5_SDK_17.1.0_ddde560. For compatible downloads of your required product, you can check the Nordic Homepage <a href="https://www.nordicsemi.com/Products/nRF51822/Download?lang=en#infotabs">here</a>.&nbsp;The nRF51822 supports upto SDK version 12.3.0.</span></p> <p><span>Regards,</span></p> <p><span>Priyanka</span></p><div style="clear:both;"></div>
