the chip just sits on top, have to push it down with your finger to get a good connection - it gets us by to do some quick firmware flashing, would be painful to hold in place if you plan to connect through serial and run a series of commands though. Removing the solder was a pain, we used a heat gun and solder iron and lost some of the small capacitors while doing it.
There’s probably a better way to build something on a separate board using those same 20-pin parts and solder some jumpers from the DWM1001-DEV (or use a J-link mini connector), but the one we did works good enough for our needs so I havn’t bothered to work out something different.
