Asking how to load firmware on Holyiot nRF52832 dongle

Question

I got some Holyiot "YJ-17017-USB" dongles, which use the nRF52832. From my Windows dev environment, I want to load firmware on them (SoftDevice, etc.), but I'm not sure how. The datasheet has a Programming section www.holyiot.com/.../2019042318312862317.pdf "Holyiot-17017 module use the Serial Wire Debug(SWD port )" 
 I looked at the Serial Wire Debug document linked there: https://www.silabs.com/community/mcu/32-bit/knowledge-base.entry.html/2014/10/21/serial_wire_debugs-qKCT 
 That doc talks about a “2-pin” interface, but the "YJ-17017-USB" has a USB connection with no exposed pins at all, so I don’t understand how SWD can apply to the "YJ-17017-USB". 
 My background: I'm very new to working with Nordic products. I started working with the nRF52 series this month, and successfully did some testing with the Nordic nRF52840 dev-dongle, programmed via nRF Connect with a pre-built firmware file. 
 Thanks, 
 Paul

Hi. 
 As awneil said below, you should contact Holyiot for specific details about their product since Nordic does not have information about this :-) 
 Best regards,

You should really contact Holyiot for specific details about their product - it is beyond Nordic's scope.

 Are you familiar with any other microcontroller(s) ? 
 The SWD interface is an ARM standard - so, as far as the basics of programming go, it's no different to any other Cortex-M4. 
 Would probably be easiest to get yourself an nRF52832 Dev Kit, and follow the tutorials, etc, on that to gain familiarity with the product and the tools. 
 Once you've done that, then you'll be equipped to work out this "Holyiot" thing ...
