Review of the GitHub Repository: LLDP Stick

Introduction

The GitHub repository lldp_stick by slowbro offers a network diagnostic tool designed to provide information using the Link Layer Discovery Protocol (LLDP). This tool is particularly useful for network administrators and engineers who need to gather network topology information. The repository includes not only the source code but also detailed instructions for building and assembling the device.

Features and Benefits

Comprehensive Network Diagnostics:

• The primary goal of the LLDP Stick is to display LLDP information, which includes details about the connected network devices. Future enhancements aim to support additional diagnostics via Bluetooth Low Energy (BLE), such as setting/resetting MAC addresses, DHCP, and ping functionalities.

Power Efficiency:

• Significant improvements have been made in power consumption across different revisions. For instance, power draw has been reduced from 34mA in revision 0 to 150µA in revision 3, making the device more suitable for battery-operated applications.

Ease of Assembly:

• The repository provides detailed assembly instructions, including the required components like the PCB, OLED display, buttons, LED, battery, and 3D printed case. This makes it accessible even for those with moderate hardware assembly skills.

Open Source and Customizability:

• As an open-source project, users can customize the tool according to their specific needs. The repository includes all necessary files, such as Gerber files for PCB manufacturing and the source code for firmware development.

Technical Highlights

LLDP Protocol: The LLDP Stick utilizes the LLDP protocol to gather and display information about neighboring network devices. This is crucial for network topology discovery and management.

Bluetooth Low Energy (BLE): Future updates aim to leverage BLE for additional diagnostic capabilities, allowing for wireless communication and control via a phone app.

Power Management: The project has focused on reducing power consumption, which is crucial for portable and battery-operated network diagnostic tools.

Conclusion

The lldp_stick repository provides a valuable tool for network diagnostics, with a focus on power efficiency and ease of assembly. Its comprehensive documentation and open-source nature make it an excellent resource for network professionals looking to enhance their diagnostic capabilities with custom tools.
