The GPS signal is applied to the antenna input of module, and a plete serial data message with position, velocity and time information is presented at the serial interface with NMEA protocol or custom protocol. It is based on the high performance features of the Media Tek MT3339 single-chip architecture, Its - 165d Bm tracking sensitivity extends positioning coverage into place like urban canyons and dense foliage environment where the GPS was not possible before. The small form factor and low power consumption make the module easy to integrate into portable device like PNDs, mobile phones, cameras and vehicle navigation systems. Applications - Portable devices - LBS (Location Based Service) - PND (Portable Navigation Device) - Vehicle navigation system - Timing application Figure 1: SKM52 Top View Features - Ultra high sensitivity: -165d Bm - Extremely fast TTFF at low signal level - Built in high gain LNA - Low power consumption: Typical 20m A@3.3V - NMEA-0183 pliant protocol or custom protocol - Operating voltage: 3.0V to 4.2V - Operating temperature range: -40 to 85℃ - Small form factor: 20x20x4.9mm - Ro HS pliant (Lead-free) Pin Assignment Figure 2: Bottom View 2 DS-SKM52-V1-120805 .skylab..cn Skylab SKM52 Pin Description Pin No. 1 2 3 4 5 6 Pin name VCC GND RXD TXD VBACKUP...
