[0027] This utility model proposes a positioning module with an M.2 interface.

[0028] In the embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 As shown, the positioning module of the M.2 interface includes a gold finger interface 1, a voltage regulator module 2, and a positioning module 3. The gold finger interface 1 is connected to the positioning module 3. The voltage regulator module 2 is located between the gold finger interface 1 and the positioning module 3.

One end of the first resistor R16 is connected to the gold finger interface 1, and the other end of the first resistor R16 is connected to the second positioning input pin 11. The second positioning input pin 11 is used for... A wake-up signal is transmitted between the gold finger interface 1 and the positioning module 3.

[0030] This invention employs a positioning module with an M.2 interface. The positioning module 3 has a first positioning input pin 31 for receiving or transmitting positioning information. The gold finger interface 1 has a second positioning input pin 11 and a first resistor R16. One end of the first resistor R16 is connected to the gold finger interface 1, and the other end is connected to the second positioning input pin 11.

[0031] like Figure 3 As shown, the voltage regulator module 2 includes a first filter circuit, a voltage regulator chip U1, and a second filter circuit connected in sequence. The first filter circuit is connected to the WIFI input signal.

[0032] The first filter circuit includes a first capacitor C11, a second capacitor C12, and a third capacitor C13, which are connected in parallel. The first terminal of the first capacitor C11, the first terminal of the second capacitor C12, and the first terminal of the third capacitor C13 are respectively connected to the power supply terminal of the voltage regulator chip U1, and the second terminals of the first capacitor C11, the second terminal of the second capacitor C12, and the third terminal of the third capacitor C13 are all grounded.

[0033] The first capacitor, C11, is used for power supply decoupling or high-frequency filtering. It can filter out high-frequency noise from the power supply or signal lines, making the circuit operation more stable. Especially when there is high-frequency noise or instability in the power supply, the first capacitor C11 can effectively smooth the voltage and reduce unnecessary interference. The second capacitor, C12, is used for intermediate frequency signal filtering. For signal processing, the second capacitor C12 can control the range of signal passage by adjusting the cutoff frequency. The third capacitor, C13, is used for low-frequency stability or signal smoothing, avoiding signal fluctuations and instability. It can also be used to smooth the power supply voltage, especially when the power supply voltage varies greatly, providing voltage stability.

[0034] The second filter circuit includes a fourth capacitor C15, a second resistor R3, and a third resistor R11. The first terminal of the fourth capacitor C15 is connected to the voltage regulator chip U1. The first terminal of the second resistor R3 is connected to the first terminal of the third resistor R11 and the first terminal of the fourth capacitor C15. The second terminal of the second resistor R3 is connected to the output terminal of the voltage regulator chip U1. The second terminals of the third resistor R11 and the second terminals of the fourth capacitor C15 are both grounded.

[0035] The fourth capacitor, C15, is typically used in the second filter circuit to filter high-frequency noise by providing a low-impedance path for the high-frequency signal, thus removing high-frequency components. The fourth capacitor, C15, can also be used with the second resistor, R3, and the third resistor, R11, to form low-pass, high-pass, band-pass, or band-stop filters. Specifically, in a low-pass filter, the capacitor is typically used to guide the high-frequency signal to ground, thereby reducing unwanted high-frequency components. The second resistor, R3, is used to adjust the cutoff frequency of the fourth capacitor, C15. The value of the resistor determines the charging and discharging time of the capacitor, thus affecting the frequency response of the filter. In a low-pass filter, the second resistor, R3, helps determine the attenuation characteristics of the signal near the cutoff frequency, affecting the filter's bandwidth and attenuation level. The third resistor, R11, is used to further adjust the impedance characteristics of the circuit, ensuring circuit stability and helping to optimize the filter's response.

[0036] The second filter circuit further includes a fifth capacitor C8, a sixth capacitor C9, and a seventh capacitor C14. These capacitors are connected in parallel. The first terminals of the fifth capacitor C8, the sixth capacitor C9, and the seventh capacitor C14 are respectively connected to the output terminal of the voltage regulator chip U1. The second terminals of the fifth capacitor C8, the sixth capacitor C9, and the seventh capacitor C14 are all grounded. The first capacitor C11, the second capacitor C12, the third capacitor C13, the fourth capacitor C15, the fifth capacitor C8, the sixth capacitor C9, and the seventh capacitor C14 are electrolytic capacitors.

[0037] Electrolytic capacitors smooth out pulsating voltage after rectification, reducing voltage fluctuations and making the output voltage more stable. Electrolytic capacitors can be used for signal coupling, transferring a signal from one circuit to another while preventing DC interference. They can also store electrical energy and release it when needed, providing short-term current support, especially useful in circuits requiring rapid response.

[0038] The voltage regulator chip U1 is model number BL1117-ADJ.

[0039] The positioning module 3 is equipped with an antenna clip, which is used to output or input wireless signals. The antenna clip is used to fix and support the antenna, ensuring that the antenna maintains a stable position and angle during use, and preventing the antenna from shifting or being damaged due to external forces.

[0040] like Figure 5 As shown, the positioning module further includes a third filtering circuit, which is connected to the positioning module 3. The third filtering circuit includes a magnetic bead FB1, an eighth capacitor C1, a ninth capacitor C2, and a tenth capacitor C3. The magnetic bead FB1 is connected to the eighth capacitor C1, the ninth capacitor C2, and the tenth capacitor C3, respectively, and the eighth capacitor C1, the ninth capacitor C2, and the tenth capacitor C3 are connected in parallel.

[0041] FB1 ferrite beads are used to filter high-frequency interference in current. They suppress high-frequency noise by using the magnetic material inside to create impedance to high-frequency signals. FB1 ferrite beads can effectively prevent the propagation of high-frequency electromagnetic interference in the power supply, thereby improving the system's electromagnetic compatibility.

[0042] The eighth capacitor, C1, is used to smooth voltage ripples and noise in the power supply. Its function may include filtering low-frequency noise or smoothing the rectified voltage to ensure the required stable voltage in the circuit. It may also provide decoupling for different parts of the circuit, preventing high-frequency noise from being transmitted to sensitive circuit sections through the power lines. The ninth capacitor, C2, also provides filtering, but it may be optimized for different frequency ranges or different circuits. Connected in series or parallel in the circuit, it helps to further reduce noise in the power supply or stabilize the signal. The tenth capacitor, C3, decouples power supply noise, helping to reduce voltage fluctuations or abrupt changes in the power supply lines, especially in digital circuits, preventing power supply noise from affecting circuit stability.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
