https://devzone.nordicsemi.com/f/nordic-q-a/47235/nrf-52-51-compatibility-question1. Do I need to make hardware changes when I want to change my SoC chipset with nRF 51 to nRF 52? 2. Does the nRF52 Series require hardware changes when it needs to change to another chipset(for example, nRF52840-&gt;nRF52832 or nRF2840-&gt;nRF52811)?en-USTelligent Community 13Mon, 19 Aug 2019 02:02:49 GMThttps://devzone.nordicsemi.com/thread/204608?ContentTypeID=1Mon, 19 Aug 2019 02:02:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:71db5137-ebbe-4c20-96a1-3b4c7286cd1atony55723<p>Excuse me, if it is software nRF2840-&gt;nRF52811, SDK15.3.0, what changes do I need to make in the project?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/187101?ContentTypeID=1Wed, 15 May 2019 02:33:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:47a5afe4-17fb-4dbc-aa0a-5c4be81cd303alan.kim<p>thank you for your advice :-)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/186870?ContentTypeID=1Tue, 14 May 2019 08:44:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7fa1ee80-238d-4fd9-8f72-486d5387155bawneil[quote userid="79690" url="~/f/nordic-q-a/47235/nrf-52-51-compatibility-question"]SoC chipset[/quote] <p>To be pedantic, note that it&#39;s a single <em>chip</em> - not a set!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/186859?ContentTypeID=1Tue, 14 May 2019 08:13:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5f774032-30d3-4389-b665-78b393c62ff2haakonsh<p>1. The nRF52832 is not drop-in compatible with the nRF51 series, nor the rest of the nRF52 series, with the exception of the nRF52810.&nbsp;<br /><br />2. The nRF52840 is not drop-in compatible with any other device.&nbsp;<br /><br />You will need new boards for the nRF52 series.
