https://devzone.nordicsemi.com/f/nordic-q-a/62754/120-degree-temperatureFrom the documentation i have found it seems all the nrf52 and the new nrf5340 are all &quot;extended range&quot; up to 105 degrees celcius. I am evaluating an application where a nrf52 or nrf53 will be used to monitor temperature and humidity in a tool useden-USTelligent Community 13Thu, 18 Jun 2020 13:16:41 GMThttps://devzone.nordicsemi.com/thread/255789?ContentTypeID=1Thu, 18 Jun 2020 13:16:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:85ff27f3-a4b4-4c43-a387-ae9762433602ketiljo<p>The radio will have a hard time operating at these temperatures, even at low voltage.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/255750?ContentTypeID=1Thu, 18 Jun 2020 11:42:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8cd3f900-cc2f-4971-9d44-630ecfdabdc6bobdk<p>we can get the external components we need with support for 125 degrees, incl battery.
