1.2 Power Supply
Regulated power for the HR-45R2-U20-W014 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 3.3V~5.5V, Recommended power supply voltage is 5.0V. maximum current is 40mA. Suitable decoupling must be provided by external decoupling circuitry.
The module supports two full-duplex serial channels RS232. All serial connections are at 5.0V TTL 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 module's default baud rate is set up 9600bps, however, the user can change the default baud rate to any value from 4800 bps to 38400kbps. RS232 is used e.g. for booting and NMEA interface.
The Gmouse is equipped with a Molex 2*2 Pin connects to your application platform.
The HR-45R2-U20-W014Gmouse It consists of a G7020-KT single-chip GPS IC which includes the RF part and Baseband part, a SPI FLASH, a patch antenna, a LNA, a SAW filter, a TCXO, a crystal oscillator, a RS232 level conversion chip, Also comes with a 0.22F crystal capacitor ,can backup satellite ephemeris about 2 hour.
