However, the drawings are only provided for reference and explanation and are not intended to limit the present invention.

[0018] Figure 1 This is a circuit structure diagram of the mainboard diagnostic card of the utility model. DETAILED DESCRIPTION

[0019] In order to further illustrate the technical means and effects adopted by the present invention, the preferred embodiments of the present invention and the accompanying drawings are described in detail below.

[0020] like Figure 1 As described above, the motherboard diagnostic card 1 of the utility model includes a wireless communication SoC chip 10 , a USB adapter 21 , an antenna 22 , a UART to USB chip 23 and a first USB connector 28 .

[0021] Among them, the wireless communication SoC chip 10 is connected to the USB adapter 21 via the UART connector 20, and the USB adapter 21 is used to connect to the USB connector of the mainboard 50 to obtain the serial port information of the mainboard 50 from the mainboard 50; the wireless communication SoC chip 10 is connected to the antenna 22 via its WIFI interface 11, and establishes a communication connection with the cloud terminal 60 through the antenna 22 to receive serial port commands from the cloud terminal 60 and upload the serial port information to the cloud terminal 60; the wireless communication SoC chip 10 is connected to the first USB connector 28 via the UART to USB chip 23, and the first USB connector 28 is used to connect to an external computer 70 for debugging the wireless communication SoC chip 10 and for the external computer 70 to read the serial port information, and the first USB connector 28 is also used to connect to an external power supply 80; the mainboard diagnostic card 1 obtains power from the mainboard 50 through the USB adapter 21, or obtains power from the external power supply 80 through the first USB connector 28.

[0022] Therefore, the mainboard diagnostic card 1 of the present invention can easily and quickly obtain serial port information from the mainboard 50 and upload it to the cloud terminal 60 through the setting of the wireless communication SoC chip 10, so that engineers can call and analyze it and discover abnormalities or problems in time; moreover, the mainboard diagnostic card 1 of the present invention can realize the debugging of the wireless communication SoC chip 10 and transmit the obtained serial port information to the external computer 70 in real time by setting the UART to USB chip 23; in addition, the mainboard diagnostic card 1 of the present invention can have two power supplies, so it can avoid the situation where when obtaining serial port information from the mainboard 50, the mainboard diagnostic card 1 is powered off and reset due to the power failure of the USB connector on the mainboard end, causing the loss of serial port information.

[0023] Furthermore, the mainboard diagnostic card 1 may also include a Flash memory 25, the wireless communication SoC chip 10 is connected to the Flash memory 25, and the Flash memory 25 is used to store initialization configuration information and WIFI network configuration information of the wireless communication SoC chip 10. In one embodiment, the wireless communication SoC chip 10 is connected to the Flash memory 25 via its SPI interface 17.

[0024] Furthermore, the motherboard diagnostic card 1 may also include a TF card 24, the wireless communication SoC chip 10 is connected to the TF card 24, and the TF card 24 is used to store the serial port information. In this way, the motherboard diagnostic card 1 can be used for the cloud terminal 60 to which it is wirelessly connected or the external computer 70 connected through the first USB connector 28 to read the serial port information stored in the TF card 24. In one embodiment, the wireless communication SoC chip 10 can be connected to the TF card 24 by reusing the SPI interface 17.

[0025] Furthermore, the mainboard diagnostic card 1 may also include a reset button 26, and the chip enable interface 13, the network configuration reset interface 14 (which can be implemented through the corresponding GPIO interface) and the Flash burning permission interface 15 (which can be implemented through the corresponding GPIO interface) of the wireless communication SoC chip 10 are connected to the reset button 26. By operating the reset button 26, the wireless communication SoC chip 10 can be reinitialized, and the network configuration can be reset and the networking operation can be re-performed. When the Flash memory 25 needs to be re-burned through the first USB connector 28 and the UART to USB chip 23, a signal allowing the start of Flash burning can also be sent through the reset button 26.

[0026] Furthermore, the motherboard diagnostic card 1 may also include an LED light 27, and the wireless communication SoC chip 10 is connected to the LED light 27. The LED light 27 can be used to provide a prompt for the normal operation of the wireless communication SoC chip 10 and a prompt for successful network configuration. In one embodiment, the wireless communication SoC chip 10 is connected to the LED light 27 via its GPIO interface 16.

[0027] Specifically, the wireless communication SoC chip 10 is connected to the UART connector 20 via a multiplexed XTAL signal interface 18. In addition, the wireless communication SoC chip 10 can also reserve two GPIO interfaces for the UART connector 20 for standby. It is briefly explained here that the serial port signal and the USB data signal of the processor of the mainboard 50 can be selected to be sent to the USB connector of the mainboard 50 through the switching switch. In this way, when the USB adapter 21 is connected to the USB connector of the mainboard 50, the switching signal of the switching switch can be changed so that the switching switch switches the USB data signal and the serial port signal, so that the serial port information can be transmitted to the mainboard diagnostic card 1 through the USB connector of the mainboard 50. The mainboard diagnostic card 1 can also obtain power from the mainboard 50 through the USB adapter 21.

[0028] After receiving the serial port information from the mainboard 50, the wireless communication SoC chip 10 can upload the serial port information to the cloud terminal 60 in real time through the antenna 22. Moreover, the mainboard diagnostic card 1 can receive serial port commands from the cloud terminal 60 to achieve the control of the mainboard diagnostic card 1 by the cloud terminal 60. If multiple mainboard diagnostic cards 1 simultaneously transmit serial port information of different mainboards 50 to the cloud terminal 60, each mainboard diagnostic card 1 can be named for the cloud terminal 60 to distinguish and control. Preferably, the antenna 22 is a ceramic patch antenna, which can save space and has good stability.

[0029] The wireless communication SoC chip 10 is connected to the UART to USB chip 23 via its UART interface 12. The UART to USB chip 23 is connected to the first USB connector 28, which is used to connect to an external computer 70, and can be used to debug the wireless communication SoC chip 10 and burn the internal information of the Flash memory 25, including the initialization configuration information of the wireless communication SoC chip 10, WIFI network configuration information, etc.; and it can also be used for engineers to directly read the serial port information from the mainboard diagnostic card 1 on the external computer 70. For example, when the mainboard diagnostic card 1 is plugged into the mainboard 50 through the USB adapter 21 and connected to the external computer 70 through the first USB connector 28, the engineer can directly read the serial port information of the mainboard 50 through the external computer 70 through signal switching or selection for analysis; the engineer can also read the serial port information stored in the TF card 24 in the mainboard diagnostic card 1 through the external computer 70.

[0030] The first USB connector 28 is also used to directly connect to an external power supply 80, and use the external power supply 80 to power the mainboard diagnostic card 1. This can avoid the situation where the mainboard diagnostic card 1 only obtains power from the mainboard 50 while obtaining serial port information from the mainboard 50. If the USB connector of the mainboard 50 loses power, the mainboard diagnostic card 1 will also lose power and reset, resulting in the loss of serial port information.

[0031] In one embodiment, the first USB connector 28 may be a TYPEC connector.

[0032] Preferably, the wireless communication SoC chip 10 is an Espressif ESP32-C3 chip, which supports common interface functions such as SPI, UART, I2C, and has 22 or 16 GPIO ports and integrated Wi-Fi and Bluetooth communication functions.

[0033] Specifically, the ESP32-C3 chip is connected to the UART connector 20 through a multiplexed XTAL signal interface, and two GPIO interfaces are reserved for the UART connector 20 for standby; the ESP32-C3 chip is connected to the antenna 22 through a WIFI interface; the ESP32-C3 chip is connected to the UART to USB chip 23 through its UART interface; the ESP32-C3 chip is connected to the Flash memory 25 through an SPI interface, and is connected to the TF card 24 by multiplexing the SPI interface; the ESP32-C3 chip is connected to the reset button 26 through a chip enable interface and two GPIO interfaces that serve as a network configuration reset interface and a Flash burning interface respectively; the ESP32-C3 chip is also connected to the LED light 27 through two GPIO interfaces.

[0034] Therefore, the motherboard diagnostic card 1 of the utility model can quickly obtain the serial port information of the motherboard based on the ESP32-C3 chip, upload the serial port information to the cloud terminal, and save it locally to facilitate engineers to call and analyze and find abnormalities or problems in time.

[0035] In a preferred embodiment, the model of the UART to USB chip 23 can be CH343P. In particular, the CH343P chip can be used in conjunction with the ESP32-C3 chip in the motherboard diagnostic card 1 of the utility model to achieve corresponding functions.

[0036] In summary, the motherboard diagnostic card of the utility model can conveniently and quickly obtain serial port information from the motherboard and upload it to the cloud terminal through the setting of the wireless communication SoC chip, and can also be saved locally for engineers to call and analyze and find abnormalities or problems in time. Preferably, the wireless communication SoC chip is an ESP32-C3 chip. The motherboard diagnostic card of the utility model can quickly obtain the serial port information of the motherboard end based on the ESP32-C3 chip, and upload the serial port information to the cloud terminal, and can be saved locally at the same time, so that engineers can call and analyze and find abnormalities or problems in time; Moreover, the motherboard diagnostic card of the utility model can realize the debugging of the wireless communication SoC chip and transmit the acquired serial port information to an external computer in real time by setting a UART to USB chip, and can also be used for an external computer to read the serial port information saved in the motherboard diagnostic card; In addition, the motherboard diagnostic card of the utility model adopts a dual power supply solution, which can avoid the situation where the serial port information is lost when the USB connector on the motherboard end is powered off and reset together, resulting in the loss of serial port information.
