50 Channel D2523T Helical GPS Receiver

The D2523T is a compact GPS smart-antenna engine board, which comes equipped with a Sarantel GeoHelix high-gain active antenna and GPS receiver circuits. The module is based around the high performance 50-channel u-blox 5 platform.

The omni-directional antenna provides great sensitivity, even when you don't have a clear view of the sky. Whether this receiver is in your pocket or under your car seat, you are likely to pickup a rock solid GPS signal.

The module operates at 3.3VDC and outputs standard format NMEA strings over the TTL/UART pins. It has up to a 4Hz update rate.

This GPS module has a connector similar to that on the EM-406, so you can use the same interface cable to connect to it.
