This applies to all nRF5x devices.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/122668?ContentTypeID=1Fri, 02 Mar 2018 20:04:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a6c01949-2797-498d-bad9-b05a6852c15bRicFlair<p>Does the RF51822 also operate within the Sub 1Ghz bands?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/62402?ContentTypeID=1Sun, 11 Sep 2016 11:13:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b8eadb9e-6798-4109-8ce0-40bb58ec9c89Roger Clark<p>As far as I&#39;m aware the only sub 1GHz Nordic product is the nRF9E5</p> <p>However, I think it would be quite hard to write mesh software to run on this device as the spec says it only has</p> <blockquote> <p>256-byte data ram</p> </blockquote> <p>See <a href="http://www.nordicsemi.com/eng/nordic/download_resource/10455/2/53641711">http://www.nordicsemi.com/eng/Products/Sub-1-GHz-RF/nRF9E5</a></p> <p>The Nordic nRF905 is the same device but without the built in MCU, so you could pair it with an external MCU e.g. I suppose you could use a nRF51822 as the MCU and not use the BLE. or use an nRF52832</p> <p>Or use a separate MCU from another manufacturer.</p> <p>But I don&#39;t think you will be able to do what you want with just one Nordic product</p><div style="clear:both;"></div>
