UBLOX LEA-5A GPS receiver module

The LEA-5A is a stand-alone, compact GPS receiver module designed to allow easy, straightforward migration from its LEA-4S and LEA-4A predecessors. It provides lower cost than LEA-5S and the built-in antenna supervisor supports external, active antennas, such as u-blox' high performance GPS antenna.

The LEA-5A features u-blox' ^? Indoor GPS technology that offers unmatched tracking performance in harsh signal environments such as parking lots and dense urban environments. The module's architecture further ensures costs are kept at a minimum by using a crystal instead of a TCXO and replacing a costly Flash EPROM by an internal read-only memory (ROM) in the GPS baseband chip.
