Afraid not - ideally you'd connect the GND, SWD, and SWCK pads to something like an nRF52832DK board, then you can use
make flashto flash it over SWD (which takes ~15 seconds). It's even possible to debug.Having said that, I actually do a lot of development on a nRF52832DK board as it's easier, and then flash the Pucks only when needed (I made a jig with pogo pins to make it faster/easier)
