https://devzone.nordicsemi.com/f/nordic-q-a/120969/flash-to-nrf5280-on-xiao-sense-plus-with-development-kitHi I want to know if I can use the nRF52850-DK to flash the Xiao Sense Plus from seeed? I am following the following tutorial which says I need to use a J-Link but that&#39;s really expensive: https://wiki.seeedstudio.com/xiao-ble-sidewalk/#flash-firmwareen-USTelligent Community 13Fri, 25 Apr 2025 11:51:20 GMThttps://devzone.nordicsemi.com/thread/533000?ContentTypeID=1Fri, 25 Apr 2025 11:51:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4e31c3d0-ffb1-4995-85c7-da7c4bcb682aSimonr<p>Hi</p> <p>If the Xiao sense Plus is running at 3.0V then you should be able to flash it using the nRF52840 DK. You can connect it as in the image below and the interface MCU debugger on the nRF52840 DK should detect it and program the external board (Xiao) by default.</p> <p>&nbsp;<img style="max-height:240px;max-width:320px;" alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/6557.ext_5F00_52DK.png" /></p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
