1. Working environment with strong electrical interference: Some circuits contain high voltage, inverters, motor drives, or other sources of strong electrical interference. When connecting USB devices to a computer in such environments, isolation is required to protect the computer and ensure personal safety. 2. Noise-sensitive applications: Computers can generate electrical noise that affects sensitive equipment. This device isolates the USB interface to reduce interference in precision systems such as high-precision USB data acquisition systems and high-fidelity audio (HIFI) setups. 3. USB debugging tools: For JTAG/SWD emulators, ISP/ASP/IAP programmers, and similar USB-based debuggers, connection issues or abnormal behavior during debugging may be resolved by using a USB isolator. 4. Industrial USB devices: In industrial settings, USB devices such as mice, keyboards, USB-to-serial converters, and other communication peripherals are prone to failure. A USB isolator helps reduce crashes and damage caused by ground loops and electrical noise. It can also function as a USB repeater for cable extension while isolating ground potential differences between connected devices. 5. Common USB peripherals: Compatible with standard USB devices including mice, keyboards, USB sound cards, flash drives, printers, digital cameras, USB hubs, and USB webcams. Tested and supported devices: Full-speed USB devices including USB flash drives, digital cameras, memory card readers, external hard drives, USB-to-serial adapters (FT232, CP2102, PL2303, CH341), and programming tools such as AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, FET430UIF, PICKIT2, XDS100, -Link, ICD2.
