[quote user="HuNa"]I can&amp;#39;t buy a NRF52840 DK due to air transportation limitations of American[/quote]
&lt;p&gt;&amp;nbsp;Based on the digikey.com.cn link you have added I guess you are from China? We have distributors in China, &lt;a href="https://www.nordicsemi.com/eng/distributor/country/45"&gt;here is a list.&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;I recommend that you contact one of our distributors in China and buy the nRF52840 DK, this will give you more options than the J-Link Base debugger and be more reasonable.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards.&lt;/p&gt;

&lt;li&gt;I have a BMD-340-EVAL and PPK, I can&amp;#39;t buy a NRF52840 DK due to air transportation limitations of American, but I don&amp;#39;t really get what the Segger J_Link debuuger is ? I found a product :&lt;/li&gt;
&lt;li&gt;&lt;a href="https://www.digikey.com.cn/product-detail/zh/segger-microcontroller-systems/8-08-00-J-LINK-BASE/899-1004-ND/2175882"&gt;https://www.digikey.com.cn/product-detail/zh/segger-microcontroller-systems/8-08-00-J-LINK-BASE/899-1004-ND/2175882&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Can this be used as a J_Link debugger? Can you give me some recomendation? Many thanks!&lt;/li&gt;

&lt;p&gt;Could you please clarify the following, as it is a bit unclear?&lt;/p&gt;
&lt;p&gt;Do you have:&lt;/p&gt;
&lt;p&gt;1) The PPK, a nRF52840 DK, and a BMD-340-EVAL kit?&lt;/p&gt;
&lt;p&gt;2) The PPK and a BMD-340-EVAL kit?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;If you have (1), have you followed the&lt;a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.tools%2Fdita%2Ftools%2Fpower_profiler_kit%2FPPK_user_guide_PPK_on_customHW_with_nRF5xDK.html&amp;amp;cp=5_6_5_4"&gt; Measuring current on custom hardware with nRF5 DK Guide&lt;/a&gt; on the infocenter?&lt;/p&gt;
&lt;p&gt;If you have (2), have you followed the&amp;nbsp;&lt;a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.tools%2Fdita%2Ftools%2Fpower_profiler_kit%2FPPK_user_guide_PPK_on_customHW_standalone.html&amp;amp;cp=5_6_5_5"&gt;Measuring current on custom hardware without nRF5 DK Guide&lt;/a&gt; on the infocenter?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards..&lt;/p&gt;
