1. Working environment with strong electrical interference: Some circuits involve high voltage, inverters, motor drives, and other sources of strong electrical interference. When connecting to a computer, isolation is required to ensure system stability and personal safety. 2. Noise-sensitive applications: Computers can generate electrical noise that affects sensitive equipment. This device isolates the USB interface, making it suitable for high-precision USB data acquisition systems and high-fidelity o (HIFI) setups. 3. USB debugging tools: For JTAG/SWD emulators, ISP/ASP/IAP programmers, and similar USB-based debugging equipment, connection issues or abnormal behavior during emulation may be resolved by using a USB isolator. 4. Industrial USB devices: In industrial environments, USB devices such as mice, keyboards, and USB-to-serial converters are prone to failure. The USB isolator helps reduce the risk of device crashes and damage. It can also function as a USB repeater for cable extension while isolating ground potential differences between upstream and downstream 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.
