The tiny footprint is a lifesaver for my cramped enclosure, and the u.FL connector took all the guesswork out of attaching an external antenna. It paired up with my existing setup in under ten minutes, which is more than I can say for most modules I've wrestled with.

The u.FL connector made hooking up an external antenna a breeze, and the module's tiny footprint slid right into my enclosure without any hassle. I had it paired and talking to my network within minutes of soldering.

The form factor is perfect for tight enclosures, and the u.FL connector gives you the flexibility to position the antenna exactly where you need it. I've got it running in a custom sensor build and it's been rock solid for three weeks straight.
