Please refer to fig. 1, which is a schematic structural diagram of the COM-E core board based on the fly-by platform according to the present utility model. As shown in fig. 1, in the COM-E core board based on the fly-by platform according to the first embodiment of the present utility model, at least one of the fly-by processor, the COM-E connector, the bridge chip, the gigabit ethernet control chip, and the PHY chip is provided with a COM-E connector AB port and a COM-E connector CD port, and the fly-by processor and the bridge chip are electrically connected between the COM-E connector AB port and the COM-E connector CD port, and the PHY chip is disposed between the fly-by processor and the COM-E connector CD port.
In order to expand the peripheral port functions of the COM-E core board, the Feiteng processor is provided with a PCIE3.0 port, a UART0 port and a UART1 port, and the PCIE3.0 port, the UART0 port and the UART1 port are electrically connected with the COM-E connector AB port.
The Feiteng processor is provided with an SPI port, an LPC port, a CAN port and a GPIO port, and the SPI port, the LPC port, the CAN port and the GPIO port are electrically connected with the CD port of the COM-E connector.
The bridge piece is provided with a UART1 port, a UART2 port, a DP0 port, a DP1 port, a DP2 port and a USB port, and the UART1 port, the UART2 port, the DP0 port, the DP1 port, the DP2 port and the USB port are all electrically connected with the CD port of the COM-E connector.

Through PCIE3.0 port, USB2.0 port, SATA3.0 port, SMBus port and I2S audio port, the COM-E core board can be connected with other electronic equipment to perform information interaction
The bridge piece is also electrically connected with the LPDDR 4.
And a 3.3V-1.8V level conversion module is also arranged between the bridge piece and the CD port of the COM-E connector. Fig. 2 is a working schematic diagram of a 3.3V-1.8V level conversion module used in a COM-E core board based on a fly-by platform according to the present utility model. As shown in fig. 2, for the level shift application circuit, the gate-source voltage (GateSourceVoltage, VGS) is mainly focused on the selection parameter of the fet, and the value of the fet cannot be too small, otherwise the fet cannot be turned on (or has a larger resistance) because VGS is smaller than the gate threshold voltage (gatehold). The basic principle of the bidirectional level shift circuit is first to look at the level shift principle from left to right (1.8V to 3.3V). When the left side D0 inputs the high level "H", the fet VT1 is non-conductive because VGS is 0, and the right side D1 is pulled up to the high level (3.3V) by the resistor R2. When the left side D0 inputs the low level "L", the fet VT1 is in the on state because VGS is 1.8V, and the right side D1 is pulled down to the same low level as D0, as shown in fig. 2, and fig. 2 is.
Looking again at the level shift principle from right to left (3.3V to 1.8V). Assuming that the left side D0 is high, when the right side D1 inputs the high level "H", the fet VT1 is non-conductive because VGS is 0, and the left side D0 is pulled up to the high level (1.8V) by the resistor R1. When the right side D1 inputs a high level "H", the conversion process needs to be subdivided into two stages. Since the left side D0 is initially high "H", VGS is 0, the fet VT1 is non-conductive, but since the fet has a parasitic diode that pulls D0 down to a low level (about one diode drop above D1, here tentatively 0.7V), D0 is also low. Next, VGS (3.3V-0.7v=2.6v) is larger than the gate threshold voltage of the fet to turn on the fet VT1, and the level of D0 is further reduced (basically no difference from D1).
The Feiteng processor is also electrically connected with a memory bank socket, and the memory bank socket is provided with a memory bank.
The COM-E connector also comprises a power supply electrically connected with the COM-E connector. The power supply is led out by using an M12 connector, and the model can be the Shanghai welcome method electric RE-PS2547, and the power supply range DC is 9-36V.

In specific implementation, the DP interface may include a 3-way displayport1.4hbr2 display interface, where: the two paths are 4Lane, and the maximum support is 3840 multiplied by 2160@60Hz; one path is 1Lane, and the maximum support is 1366×768@60HzS.

In the implementation, a 1.8V-VPP level conversion module is also arranged between the Feiteng processor D2000 and the memory bank socket. VPP is a symbol that refers to the voltage from the lowest value to the highest value of an alternating or pulsed signal, also known as the peak-to-peak value. The definition of VPP is slightly different for different chips, such as voltage peak-to-peak. The 1.8V-VPP level conversion module is similar to the operation principle of fig. 2, and will not be described here again.
