I'm using this module with a Raspberry PI B+ in order to have a NTP Stratum 1 server. With the integrated antenna I can't detect satellites but with an external antenna on SMA port it's good (9 detected, 8 used). I'm using too the PPS output and it's working fine.

It's an excellent module (I've bought more of it) that has built in antenna (that works after soldering a capacitor) but best used with external antenna. I use the 1pps signal to provide very precise time reference. Highly recommended by me for this.
