- A current nRF52840 prototype reports SWO trace up to 1 Mbaud; the page says production-board figures may change.
Field notes
The dongle is presented as a standard CMSIS-DAP v1/v2 adapter, with USB HID or bulk interfaces and two CDC serial ports. The page gives prototype measurements for memory reads, writes, and single-step timing, and says those figures will be updated for the production board. Phantom Studio is described as handling flashing, memory dumps, SWO capture, radio diagnostics, and firmware updates; its first public Windows build is still forthcoming.
