Fast, reliable connections: 20-pin hook cable kit lets you connect quickly to headers and test points so setup time is reduced and you can start capturing signals without fuss. Stable test performance: the retractable clip grips test points firmly to prevent slips and noisy contacts during measurements, improving the consistency of your captures. Built for compatibility: designed for use with Compnt USB logic analyzers and customizable for a variety of test scenarios, so it integrates directly with your existing test equipment. Durable construction: copper wire resists high temperatures and oxidation while retaining its shape over repeated use, ensuring long service life and predictable probe behavior. Practical size and function: 20-pin format covers common logic-analyzer headers without extra adapters; the hook-style connectors reach into tight pin rows and crowded PCBs. Saves time and reduces errors: faster hookups and secure clips mean fewer interrupted captures, fewer false negatives, and more reliable debugging sessions. Easy to customize: suitable for rearranging or extending connections when you switch between projects, prototypes, or production boards. Typical applications Embedded systems debugging: capture SPI, I2C, UART, and GPIO activity directly from microcontroller headers during firmware development and troubleshooting. PCB testing and validation: probe signals on populated boards, test production samples, or verify prototypes where stable, repeatable connections are required. Field service and repair: make quick, dependable signal checks on customer devices or lab equipment without soldering or permanent modifications. Specifications and compatibility summary Connector kit: 20-pin hook cable Clip type: retractable hook clip for secure test-point contact Conductor material: copper wire with high-temperature and oxidation resistance Intended use: for use with Compnt USB logic analyzers; customizable for a variety of test scenarios What you gain Faster setups, steadier captures, and longer-lasting probes that help you diagnose issues faster and with greater confidence.
