==Product Name==

LC USB to Ethernet module, serial port transparent wireless communication W5500 Ethernet chip, DC-DC power chip, 7-28V input

==Overview==

The LC USB to Ethernet module uses STM32F103C6T6 as the main control chip, equipped with CH340K to achieve USB to TTL conversion, and uses W5500 Ethernet chip; This module can serve as a TCP server. By connecting a USB cable to a computer and a network cable, data can be exchanged between the USB interface and the TCP server; This product supports DC7-28V power supply mode+Type_C port power supply

==Module usage instructions==

1. '''Program burning - USRT:''' Prepare a USB to TTL module (such as CH340) and plug it into the computer's USB port. The connection method to the module is as follows: 

{| class="wikitable" style="width:500px"

|-

|TTL serial port module || 4G development board

|-

| GND || GND

|-

| TX || RX

|-

| RX || TX

|-

| 3.3V || 3.3V

|} 

Then plug in the jumper cap between the BOOT0 pin and 3.3V to burn the firmware 

2.''' Program burning - SWD:''' Prepare a Link debugger (ST Link, J-Link, etc.) and plug it into the USB port of the computer. The Link and module connection method is as follows: 

{| class="wikitable" style="width:300px"

|-

|Link debugger || 4G development board

|-

| GND || GND

|-

| SWCLK || DCK

|-

| SWDIO || DIO

|-

| 3.3V || 3.3V

|} 

Then select the firmware for burning 

3. '''Debug:''' After connecting the Link burner in the above way, click the 'Debug' key of the compiled software, select 'ST Link', and then click Settings

4. '''Module Function Testing''' 

Connect the module as shown in the following figure and open the "serial debugger" software:

USB interface: After opening the serial port debugger, select the corresponding port and choose "9600" bit rate, then click to open the serial port. If the network connection is successful, it will return a "ready" message, and you can start sending data to the server (RJ45 network port) 

RJ45 Ethernet port: After opening the serial debugger, select the port number "TCPClient", enter "192.168.0.72:5000" in the remote box, click on the connection, and the bottom will display that the connection is successful. After that, you can send data to the USB interface 

UART interface: After power on, it will output help documents, display product information and network connection status

The above test shows that the data transmission is normal.
