Used module, untested, but removed from working device. The original antenna connector was changed with one SMA connector.
The Oncore family is a full line of GPS receivers developed and built by Motorola for the
OEM and systems integrator.
The M12 Oncore is one of the newest members of the successful Oncore family,
developed for a wide range of positioning applications.
Expanding the Oncore line with a 12-channel design, the new M12 is a small 40 x 60 x
10mm with enhanced foliage and urban canyon performance, one of the fastest TTFF
(time to first fix) in the industry, and split second reacquisition time.
Our M12 Oncore receiver is built utilizing Motorola’s custom radio frequency
integrated circuit, MRFIC1504, and the ultra-low power MCORE based MMC2003, a
32-bit RISC microcontroller. The M12 Oncore also has a 2.75 to 3.2 supply voltage and
includes support capability for inverse differential GPS, which allows for improved
positioning at a central base station to support services requiring higher accuracy such as
automotive and telematics applications. Other features, in addition to increased
embedding flexibility, include RTCM differential GPS support, NMEA 0183 output, two
communications ports, a user-controlled velocity filter, and an antenna sense circuit.

Here you can find an useful circuit to interface it with a computer o microcontroller.
BTW is simply perfect if used with Raspberry Pi!
