Soldered it onto my test board and the footprint was forgiving for hand assembly, which was a relief. Now that I've got the module talking over UART, the small form factor really pays off for cramming it into a tight enclosure. The PCB trace antenna is holding a steady connection through one plaster

The PCB trace antenna means I didn't have to add an external one, which saved me real board space in a tight enclosure. It paired and held a stable connection during a full day of testing. For the size and integration effort, this module delivers exactly what I needed.

The form factor is genuinely tiny yet the trace antenna holds a solid signal through two walls in my workshop. Integration was straightforward since the pins line up cleanly on my breakout board. Saves me a ton of space versus the older modules I’ve used.
