 I&amp;#39;m considering to get started manufacturing mini dongle nRF52840 based as in https://devzone.nordicsemi.com/f/nordic-q-a/48568/nrf52840-mini-dongle/193001#193001 .

[quote user=""]Sorry I didn&amp;#39;t get if all nRF52840 comes pre-programmed with it?[/quote]
&lt;p&gt;No. The&amp;nbsp;nRF52840 &lt;em&gt;Dongle&amp;nbsp;&lt;/em&gt;is a separate product, and this is shipped with a USB bootloader in flash. However, the nRF52840 &lt;em&gt;chip&lt;/em&gt;, in general,&amp;nbsp;is shipped with an empty flash.&lt;/p&gt;
[quote user=""]do we have to always include SWD access in order to have our devices programmed?[/quote]
&lt;p&gt;Yes. You would typically program the devices in production, often at the same time as you do production testing. You can also program the chips before they are mounted on the PCB, potentially ordering programming from another company.&lt;/p&gt;
[quote user=""]Why, if it is the case, this difference in respect to the nRF24?[/quote]
&lt;p&gt;You are right that the&amp;nbsp;nRF24L01+ is shipped with a USB bootloader. This is not done for other product though, and I cannot comment on why this is. It is not a common request, though.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
