This is a decent nRF52840 development tool; they can be easily flashed with sniffer or ncp software. It's nice to have a plastic case, but it's a little wide and makes it difficult to fit anything into the adjacent port. Since the USB port is just the end of the dongle that sticks out of the case, it can be a little loose if you're trying to run around with Wireshark and a laptop to try to figure out why something else can't see. Debugging code on it is not as easy as on a Nordic DK or a keyless MDK, but it can be solved by writing the software without errors. Or by debugging on larger platforms. Please note that this kit is for development use only and therefore does not require and have FCC certification.
