## Article

**Introduction:** Digital input Ethernet communication modules are widely used in industrial control, remote IO communication, industrial Internet of Things and other fields

### **1. Product Introduction**

Digital input Ethernet communication modules are widely used in industrial control, remote IO communication, industrial Internet of Things and other fields

### **2. Application scenarios**

Industrial control equipment, testing equipment, factory experiment equipment and industrial monitoring equipment

### **3. Product overview**

1. The power supply part uses a step-down chip LM2596, and the maximum input voltage can reach 40V

2. The power supply part has a resettable fuse

3 Circuit part design onboard W5500 Ethernet communication with SPI interface

4. With one RS232 and one serial TTL output

5. The MCU is STM32F103

6. Reserve a download interface for subsequent debugging and downloading

7. This module is a two-layer PCB board

### **4. Product parameters**

Electrical parameters:

1. Input voltage: 5V-40V

2. The power supply part is designed with a resettable fuse

3. Design with power indicator and status indicator light

4. Two-layer board design

5. Mechanical parameters: PCB size: length 120mm, width 72mm

#### **5. Instructions and Tutorials**

1. Connect power and Ethernet communication.

2. The bit TCP SERVER set by the control board DEMO program

3. Main control board IP address: 192.168.0.120, port number: 8000

4. DEBUG serial port baud rate is set to 115200,8, None,1

5. Pay attention to the positive and negative poles of the power input

6. Monitor input status through Ethernet command

### **6. Remarks**

1. The DEMO program part sends instructions for the host computer to read the input status.

2. The download tool can use ST-LINK or DAP downloader

3. The attachment contains the STM32CubeMX configuration file.

4. The cost of components is 102 yuan

5. This project needs to be used in conjunction with the "Digital Input Ethernet Communication Module (2) Expansion Board". For details of the project, see the personal homepage

### **7. Test video**

1. Read the input state through the control command
