1. Working environment with strong electrical interference: Some circuits involve 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 for system and personal safety. 2. Noise-sensitive applications: Computers can generate significant electrical noise. In sensitive measurement or audio setupssuch as high-precision USB data acquisition systems or high-fidelity (Hi-Fi) audio equipmenta USB isolator helps prevent ground loops and noise transmission through the USB interface. 3. USB debugging tools: For JTAG/SWD emulators, ISP/ASP/IAP programmers, and similar USB-based development tools, connection issues or unstable emulation may occur due to ground noise or voltage differences. A USB isolator can help stabilize communication during debugging processes. 4. Industrial USB devices: In industrial settings, USB peripherals such as mice, keyboards, USB-to-serial converters, and other communication devices are prone to malfunction or damage due to electrical noise, ground loops, or voltage spikes. A USB isolator reduces the risk of device failure. It can also function as a signal repeater to extend USB cable length 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.
