are there any plans for NRF52 USB development dongles (just like the NRF51 dongle)?
I am also interested in a an nRF52 dongle by Nordic.
We are very close to produce nRF52840 dongles without segger on board. you might be able to buy them in a month or so.
Any updates on this? Will they come preloaded with the bootloader?
Unfortunately, this has been delayed due to some unforeseen challenge. The latest news that it will be out in production in June end. Yes, they should be coming preloaded with a bootloader.
