Size 18.1X18.1X6.41mm GPS Module Antenna GPS Module GNSS module

General Description
        The Delin Comm DM1818-R is a complete GPS engine module that features super sensitivity , ultra
 low power and small form factor .The GPS signal is applied to the antenna input of module ,and a complete 
serial data message with position ,velocity and time information  is  presented  at  the  serial interface  with  
NMEA protocol or custom  protocol .
        Its -165dBm 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.

  1.2. Power Supply

       Regulated power for the DM1818-R is required. The VCC Pin Need a stable DC voltage supply. Power supply ripple must be less than 30mV. The input voltage Vcc should be 2.8V~4.3V, Recommended power supply voltage is 3.3V, maximum current is 20mA. Suitable decoupling must be provided by external decoupling circuitry.

 1.3. UART Ports

      The module supports two full duplex serial channels UART. All serial connections are at 3V CMOS logic levels, if need different voltage levels, use appropriate level shifters. The baud rate of both serial ports are fully programmable, the data format is however fixed: X, N, 8, 1, i.e. X baud rate, no parity, eight data bits and one stop bit, no other data formats are supported, LSB is sent first. The modules default baud rate is set up 9600bps, however, the user can change the default baud rate to any value from 4800 bps to 115kbps. UART port can be used for firmware upgrade, NMEA output and PMTK proprietary commands input.
