Hi,
I already got the nRF5340-DK and finished that course. Now I’m looking to build a project with my own custom board. I saw that the nRF52840 dongle can be programmed over USB, which looks really cool, and I’d like my board to be able to do the same. Do you have any tips on how to achieve that?

Hi,

I strongly recommend to order yourself an nRF52840-DK, which include full access to all pins, a programmer, a debugger, leds and buttons and easy to get started with all existing examples. The nRF52840 USB dongle is nice for demonstration after you have successfully made an application using the nRF52840-DK.
