Product Description

General Description 
   Delin Comm DM2222-R is a complete GPS engine module that features super sensitivity, ultra low power and small form factor.it with superior and performance even in urban can-yon and dense foliage environment.
    This module supports self-generate orbit prediction, EASYTM, to achieve faster cold start and warm start. The EASYTM is no need of both network assistance and host CPU's intervention. The predication is valid for up to 3 days and updates automatically from time to time when GPS module is powered on and satellites are available.

Description
Regulated power for the DM2222-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 3.0V~5.0V, Recommended power supply voltage is 3.3V . maximum current is 28mA. Suitable decoupling must be provided by external decoupling circuitry.

General Description

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.
