Module power supply (3V—5.5V)
Chapter 5 Hardware Design
It is recommended to use a DC stabilized power supply to power the module, the power supply
ripple should not exceed 30mV, and the module must be reliably grounded;
Please pay attention to the correct connection of the positive and negative poles of the power
supply. Reverse connection may cause permanent damage to the module;
Please check the power supply to ensure that it is within the recommended power supply voltage.
If it exceeds the maximum value, it will cause permanent damage to the module;
The serial ports TXD and RXD are LVTTL levels. If connected to a PC, RS232 level conversion
is required. User can use this serial port
Receive positioning information data and software upgrades.
This module is a temperature-sensitive device, and drastic changes in temperature will reduce its
performance. Try to stay away from high-temperature airflow and high-power during use.
Heating device
When designing the power supply circuit for the module, it is often recommended to reserve more
than 30% of the margin, and the whole machine is conducive to long-term stable operation;
The module should be as far away as possible from power supply, transformer, high frequency
wiring and other parts with large electromagnetic interference;
Assuming that there are devices with large electromagnetic interference around the module, it will
greatly affect the performance of the module. According to the intensity of the interference, it is
recommended to stay away from the module. If the situation permits, proper isolation and
shielding can be done；
Chapter 6 Working Mode
1. Please refer to "GK9501 Input and Output Format" in the data package for the command
format of related software functions of the module.
2. This module supports AGPS settings. For detailed setting methods, please refer to the "Goke
AGPS User Manual" in the information package.
