1. Working environment with strong electrical signals and interference: Some circuits involve high voltage, inverters, motor drives, or similar conditions where connection to a computer is required. Electrical isolation is necessary to protect the computer and ensure personal safety. 2. Noise-sensitive applications: Computers can generate significant electrical noise. In precision environments such as high-resolution USB data acquisition systems or high-fidelity audio (HIFI) setups, this device helps isolate the USB interface to maintain signal integrity. 3. USB debugging tools: For JTAG/SWD emulators, ISP/ASP/IAP programmers, and other USB-based debuggers, connection issues or abnormal behavior during development 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 the risk of malfunction and damage caused by ground loops or 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 such as USB flash drives, digital cameras, memory card readers, external hard drives, USB security keys, AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, FET430UIF, PICKIT2, XDS100, -Link, ICD2, and USB-to-serial adapters (FT232, CP2102, PL2303, CH341).
