It was a bit of a challenge to figure out what the pinout was for this module as nobody selling it seems to have it listed, if the listing had a pinout I probably would've rated it 5 stars on Quality. I eventually found a manual for the Holux M87 which gave me the pinout; 1 - Vcc 2 - TXA 3 - RXA 4 - RXB 5 - GND 6 - PPS I'm planning to use this as a GPS-locked PPS source for one of a pair of local Stratum 1 timeservers. Runs fine on 3.3V (based on the minimum voltage in the spec sheet I'd say it's got an internal 3.3V LDO regulator so YMMV module-to-module on that) Not sure if it has an internal battery or not, I'll have to do some cold start testing and see how long it takes to get a lock. Mine had a little corrosion on the case which is why I derated it on appearance. Seems to do the job, reasonably priced, pretty compact, we'll see how it goes long-term.
