https://devzone.nordicsemi.com/f/nordic-q-a/58693/difference-between-debug-p18-in-and-debug-out-p19Hi I plan to use nrf52 DK to program my device by using a connector https://www.tag-connect.com/product/tc2030-idc-nl But should I connect it to debug in or debug out? what&#39;s the difference between them?

Use debug out to connect to your board.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/238138?ContentTypeID=1Wed, 04 Mar 2020 19:30:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d3ed287a-7438-4a44-ad18-acb0dec2aa1eCindy<p>I guess it means I should use debug out, but there isn&#39;t much explain about debug in, only saying use it when nrf52 DK is on battery?
