Description:

1. The module supports GPS L1C/A L2C, GLONASS L1OF L2OF, GALILEO E1B/C E5b, BDS B1I/B2I.

2. Generally, the second group of output ports TX2 and RX2 are used to input or output RTCM data, and the first group of output ports TX1 and RX1 are used to output NMEA data.

3. The module defaults to TX1, RX1, TX2, RX2 two sets of TTL level data port work, if the customer needs RS-232 level, the jumper resistance is welded separately. If R1 and R2 stick 0R, TX1-232 and RX1-232 have RS-232 level enable. If R3 and R4 are affixed with 0R resistors, TX2-232 and RX2-232 have RS-232 level enable. TTL and RS-232 outputs cannot be enabled at the same time to avoid data conflicts. For customers who use TTL, RS-232 jumper resistors are not required.

4. The module comes with SMA-K, IPEX interface is used to connect the antenna, select one of the connectors to connect the antenna.

5. The default baud rate of the module is 38400bps. If the frequency is increased, the baud rate will be increased accordingly, otherwise the data volume will be too large to transmit. In addition, the frequency is recommended not to exceed 5HZ.

6. The module supports centimeter-level high-precision RTK differential positioning.

7. If it is used as the base station mode, it only needs to be configured into the base station mode. If the module is used as a mobile station, it can be used directly as an RTK rover, without any configuration.

8. Support custom development.
