I tried, but it failed. From the nRF52840 schematic, it looks the chip is running at 1.8V. This post says that it&#39;s not possible for the DK to program a 1.8V board.

Just power the dongle VDD from DK&#39;s VDD so the voltage is detected at VTH.</p> <p></p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/IMG_5F00_4889.JPG" /></p> <p></p><div style="clear:both;"></div>
