https://devzone.nordicsemi.com/f/nordic-q-a/52825/thingy91I have a Thingy 91 and there is switch that says it can be a Thingy52! Has anyone tried this out?en-USTelligent Community 13Thu, 03 Oct 2019 07:01:03 GMThttps://devzone.nordicsemi.com/thread/213099?ContentTypeID=1Thu, 03 Oct 2019 07:01:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5ae5198d-37ab-4056-88c0-e6aa85577a98Simonr<p>Hey Bruce</p> <p>The&nbsp;SWD selection switch doesn&#39;t set the Thingy to be a Thingy:52 per se, it rather sets if the debug connector&nbsp;goes&nbsp;to the onboard nRF52840 or the nRF9160. You can see more on how it&#39;s used in the <a href="https://infocenter.nordicsemi.com/pdf/Thingy91_UG_v1.0.pdf">Thingy:91 user guide</a>. Note that the nRF52840 is there mainly to implement BLE and NFC features on the Thingy:91, and won&#39;t be connected to all the sensors, etc. from the original Thingy:52. It is connected to a spare GPIO connector so that it can be used with various peripherals though.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
