Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] It should be noted that the terms "comprising" and "specific" in this invention, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0058] Please see Figure 1 , Figure 1 This is a schematic diagram of a multifunctional power supply system provided in an embodiment of the present invention. The multifunctional power supply system includes:

The RF antenna circuit is responsible for transmitting and receiving wireless signals; for example, the ANT_BNC and ANT WIFI_ANT antennas are used to receive and transmit Wi-Fi or other RF signals. The RF matching circuit, composed of capacitors and inductors, optimizes impedance matching of RF signals, reduces signal reflection, enhances signal transmission efficiency and stability, and ensures stable wireless communication between the chip and external devices, such as enabling device networking and data interaction with other Bluetooth or Wi-Fi devices. The power crystal oscillator circuit provides a stable clock signal to the chip. If the crystal oscillator generates a precise oscillation frequency, after adjustment with capacitors, it outputs a stable clock pulse, serving as the time reference for various functional modules within the chip. The chip uses this clock signal to coordinate the working rhythm of its internal logic circuits, ensuring orderly data processing, signal transmission and reception. The first indicator circuit indicates the device's operating status. Through the on / off state and flashing of different colored indicator lights, the operating status of the device is intuitively fed back to the user. For example, a lit blue indicator light may indicate that the device has successfully connected to a Wi-Fi network, while a flashing red indicator light may indicate a malfunction or abnormal situation. The control host module has a complex structure, encompassing multiple sub-circuits such as control and adjustment circuits and RF antenna circuits, enabling data processing and operating status control of each module.

[0110] Understandably, digital power modules provide stable DC power output to meet the power supply needs of various electronic devices for testing and maintenance. The output voltage and current can be adjusted as needed to adapt to the operating requirements of various electronic components and equipment. For example, converting the input voltage into multiple stable output voltages and using optocouplers for power enable control is suitable for scenarios requiring high power accuracy and isolation control.
