1. In environments with high electrical power and strong interference, such as those involving high-voltage systems, inverters, or motor drives, isolation is required when connecting USB devices to computers to ensure personal safety and system stability. 2. In noise-sensitive applications, such as high-precision USB data acquisition systems or high-fidelity audio (HIFI) setups, this device helps isolate the USB interface to reduce electrical noise from computers. 3. For USB debugging tools, including JTAG/SWD emulators, ISP/ASP/IAP programmers, and downloaders, a USB isolator can help resolve connection issues or abnormal emulation behavior during development and testing. 4. In industrial settings, USB devices like mice, keyboards, USB-to-serial converters, and other communication peripherals are prone to failure. A USB isolator reduces the risk of crashes and damage caused by ground loops and electrical transients. It also functions as a USB repeater for cable extension while isolating ground potential differences between connected devices. 5. Compatible with common USB peripherals such as mice, keyboards, USB sound cards, flash drives, printers, digital cameras, USB hubs, and USB webcams. Tested and supported devices include full-speed USB devices: 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.
