Precautions：

1) The radio frequency circuit on the module contains electrostatic sensitive components. Please pay attention to electrostatic protection during soldering, installation and transportation. Please donot touch the RF_IN pin with bare hands, otherwise the module may be damaged.

2) In product application, the transmission line connected to the RF_IN terminal should be controlledwith 50Ω impedance. Do not run at right angles or sharp angles, and try not to replace the signal layer. The adjacent layer below the connection line should have a complete ground plane. If thedesign is limited, at least ensure that the logo area corresponding to the following layer of theareatohave a complete ground plane. If there are other strong interference sources on the board, it isrecommended to add a shield to the interference source. If the frequency of the source of interference and the module navigation signal frequency is close, it is recommended that themoduleRF_IN front installed SAW filter.

3) Try to control the ripple of VCC power supply of the module within 100mV, and avoidinterference on the power supply.

4) Please ensure that the baud rate set by the host computer and the module is consistent.

5) It is recommended to select an active antenna with quality guaranteed BDS B1/GPSL1/GLONASS L1 frequency point (user can select the corresponding frequency point antenna according totheworkingmode), and ensure the power supply to the antenna.

6) Please control the temperature and operation mode when soldering the module to avoidmoduledamage.
