Stop Guessing, Start Testing Your USB-C Cables

We’ve all been there: a drawer full of identical USB-C cables, but only half of them actually support fast charging or high-speed data transfer. Broken internal pins are a leading cause of device connection failures. Instead of frustrating trial and error, the USB-C 24-Pin Cable Tester Board allows you to instantly verify the integrity and exact specifications of any dual-head Type-C cable.

Comprehensive 24-Pin Detection

Not all USB-C cables are created equal. This diagnostic board supports full 24-pin conductivity testing. By plugging in both ends of your cable, the module routes the connection through its precisely engineered circuit. It accurately tests every single pin, helping you identify whether a cable is fully featured (for video and heavy data) or just a basic charging cord.

Visual LED Diagnostics

Troubleshooting should be visual and immediate. The board is equipped with 12 sets of bright LED indicators mapped to specific pins (GND, TX/RX, VBUS, CC, D+/D-, SBU). If a light fails to illuminate, you immediately know exactly which internal wire is severed. Note: On standard full-featured cables, 22 indicator lights will illuminate (one side's D+ and D- lights remain intentionally unlit by design).

Portable & Battery Powered

Leave the bulky power supplies behind. Powered by a single, widely available CR2032 button battery (located on the back), this lightweight PCB module is entirely self-sufficient. Its compact footprint means you can easily slip it into a pocket, laptop bag, or toolkit, making it ideal for on-site IT support, tech retail screening, or home DIY projects.
