https://devzone.nordicsemi.com/f/nordic-q-a/126981/question-about-the-host-ic-selectionHi. I have a question about the selection of Host IC of nRF7002. Looks like general official recommendation is nRF5340. But my team has a long history with nRF52840. (Which means we have a plenty stock in our warehouse.) # Question With nRF52840en-USTelligent Community 13Thu, 12 Feb 2026 12:46:44 GMThttps://devzone.nordicsemi.com/thread/561009?ContentTypeID=1Thu, 12 Feb 2026 12:46:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f674bb2a-c0ab-46a7-a9ca-ea6efbd1a5b8SwRa<p>Hello,</p> <p>It is not recommended to use an nRF52840&nbsp;as a host for nRF7002 in your use case<span>. As you can see in this page:<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf70/constrained.html">https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf70/constrained.html</a>&nbsp;, the nRF52840 is marked as supported, but with a commend that &quot;the SoC is supported, but the use case is not recommended due to performance or memory constraints.&quot;</span></p> <p><span>It should be t</span>echnically possible to bring up Wi‑Fi (scan only)+ some BLE if you are extremely aggressive with optimization and feature trade‑offs, but again it is not recommended. F<span>or your full feature set (Wi‑Fi HTTP, multi‑central BLE, LCD, dual‑OTA, sensors),&nbsp;it definitely will not be enough. I suggest that you look at nRF5340 since it is fully supported.</span></p> <p><span>Best Regards,</span></p> <p><span>Swathy</span></p><div style="clear:both;"></div>
