Product Description

Multi-Interface USB Cable Tester Board

This USB cable tester board is designed for checking the internal wiring and connection status of different USB cables.

Simply connect both ends of the cable to the corresponding ports, turn on the tester, and observe the LED indicators. The indicator pattern helps users identify connected power lines, USB data lines, Type-C signal lines, and possible missing or abnormal connections.

It is suitable for cable inspection, electronics repair, product testing, quality control, DIY projects, and daily cable troubleshooting.

3. Identify Different Cable Functions

Different LED patterns can help identify different cable wiring configurations.

Examples:

Charging Cable

When the GND and VBUS indicators are active, the cable mainly contains power connections.

Charging and USB Data Cable

When GND, VBUS, D+ and D- connections are active, the cable contains charging and USB data wiring.

High-Speed Data Wiring

The TX and RX indicator channels can be used to check whether corresponding high-speed signal paths are connected.

Full-Featured Type-C Wiring

Additional CC, SBU, TX and RX signal connections can help identify cables with more complete Type-C wiring.

Please note that this product checks wiring connection status. It does not measure actual transfer speed, charging wattage, voltage, current, video resolution, or protocol performance.

4. Quick Cable Troubleshooting

The LED display provides a clear visual reference for checking cable wiring.

It can help identify:

• Missing connections
• Disconnected wiring
• Abnormal connection patterns
• Incomplete data lines
• Different cable wiring configurations

Suitable for quick inspection and preliminary troubleshooting.
