GPS module overview-GPS module explanation
GPS module definition
GPS module full form is Global Positioning System module, the GPS module meaning a signal receiver, which can use wireless or limited connection to transmit the signal to the cloud server for processing to achieve precise positioning.
GPS module description
The GPS module kit is a high-performance, low-power GPS, BDS BeiDou dual-mode GPS module boards. It adopts the ATGM332D-5N-31 module scheme of Zhongke Microelectronics Company, which can output GPS and BDS BeiDou positioning information to the microcontroller system and computer through the serial port, which is simple and convenient to use.

GPS module configuration for hardware
The GPS module is accurate in positioning (the GPS module range is 2.5 meters), has stable performance, beautiful device interface layout and easy to use. Its resource description is as shown in the figure:
GPS module external antenna
Active antenna: This GPS module needs to be connected to the antenna when using it, and good satellite signals can be received by using the matching active antenna.

GPS module battery
The GPS module battery is an XH414 farad capacitor with parameters: 3.3V 0.07F. Its function is the same as that of a lithium battery. When the main power supply fails, the GPS module backup battery can supply power to the RTC part of the positioning module, so that the positioning module can quickly search for satellites when it is started next time. Generally, it can last for 1 hour.
GPS module comparison
The GPS module is divided into single GPS module, BDS BeiDou module and GPS + BDS BeiDou dual module. The following is GPS module comparison of the parameter:

GPS module pinout
The GPS module uses serial port communication, and the communication pin level is TTL type, so when communicating with the computer, it needs to use the serial port line of USB to serial port TTL as the medium, the following is the physical picture of CH340 USB to TTL line.
In addition to using a TTL serial cable, you can also use a general DuPont cable to directly connect the GPS module to the development board. The following is the physical connection diagram and the connection description of the GPS module interfacing with STM32 series development board.
