The GPS module PCB assembly uses high-quality chips and has the advantages of high performance and low power consumption. This module is a complete satellite positioning receiving device with full range of functions to meet the strict requirements of professional positioning and personal consumption needs. The product can be used to develop a variety of GPS terminal products such as car navigation, vehicle monitoring and other satellite positioning applications.
GPS Module PCB Assembly Energy storage and high-frequency filter capacitors should be placed near unit circuits or devices with large current variations (such as input and output terminals, fans and relays of power modules).
The presence of a storage capacitor can reduce the loop area of the high current loop.
The filter circuit of the power input port of the circuit board should be placed close to the interface.
On the PCB, the filtering, protection, and isolation of the interface circuitry should be placed close to the interface.
Strong radiation devices such as crystals, crystal oscillators, relays, and switching power supplies are far away from the single-board interface connectors.
