1. Working environment with strong electrical interference: Some circuits involve high voltage, inverters, motor drives, or similar high-interference sources. When connecting to a computer, isolation is required to protect equipment and ensure personal safety. 2. Noise-sensitive applications: Computers can generate significant electrical noise. In precision environments such as high-fidelity o (HiFi) systems or high-precision USB data acquisition systems, this device helps isolate the USB interface to maintain signal integrity. 3. USB debugging tools: For USB-based emulators such as JTAG/SWD, ISP/ASP/IAP programmers, and downloaders, 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 may experience crashes or failures. A USB isolator helps reduce failure rates. It can also function as a USB repeater for cable extension and isolates ground potential differences between connected devices. 5. Common USB peripherals: Compatible with devices such as 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 (with FT232, CP2102, PL2303, CH341 chips), AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, FET430UIF, PICKIT2, XDS100, -Link, ICD2.
