Using nRF52840 as non RF microcontrolerhttps://devzone.nordicsemi.com/f/nordic-q-a/71506/using-nrf52840-as-non-rf-microcontrolerIf one using nRF52840 microcontroller as non-RF one, in example configuration from page 593 / Figure 214, No 6 schematic, I have two questions - does a ANT pin filtering mandatory (radio part will be completely off all the time, not used) - C3, L1,C4en-USTelligent Community 13Wed, 10 Feb 2021 13:34:38 GMTRE: Using nRF52840 as non RF microcontrolerhttps://devzone.nordicsemi.com/thread/293778?ContentTypeID=1Wed, 10 Feb 2021 13:34:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c5e4eded-1e95-4743-9543-b995396ab4c9Dimitar<p>Thanks for the fast answer, my both posts and questions were answered. No RF will be used at all, just MCU itself.</p><div style="clear:both;"></div>RE: Using nRF52840 as non RF microcontrolerhttps://devzone.nordicsemi.com/thread/293768?ContentTypeID=1Wed, 10 Feb 2021 13:12:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a43ff734-6900-43b8-a68a-040b548ff064ketiljo<p>If the radio is not used, the ANT pin can be left unconnected.&nbsp;</p> <p>As long as the center pad is grounded, it can be made smaller to fit a row of vias. Note that this is not ideal if the radio is being used.&nbsp;</p><div style="clear:both;"></div>
