1. Application

The Gmouse is equipped with a P01-P07 Connector to your application platform and power supply connection.

The HR-56R-MT Gmouse It consists of a MediaTek MTK single chip GNSS IC which includes the RF part and Baseband part, USB,RS232 level conversion chip, a patch antenna, a LNA, a SAW filter, a TCXO, a crystal oscillator, Also comes with a 0.22F crystal capacitor ,can backup satellite ephemeris about 2 hour.

2.1 Key Features

2.2 Power Supply

Regulated power for the HR-56R-MT 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 45mA. Suitable decoupling must be provided by external decoupling circuitry.

2.3 RS232 Ports

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 modules 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.

2.4 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 UBX proprietary commands input.
