1. Working environment with electrical interference: Some circuits may involve high voltage, inverters, or motor drives, creating electromagnetic interference. When connecting USB devices to a computer in such environments, isolation is recommended to help protect the computer and ensure user safety. 2. Noise-sensitive applications: Computers can generate electrical noise that may affect sensitive equipment. This device can help isolate the USB interface in applications such as precision data acquisition systems and high-fidelity o systems. 3. USB debugging tools: For USB-based debuggers and programmers such as JTAG/SWD emulators, ISP/ASP/IAP/ICP downloaders, intermittent connection issues or abnormal behavior during debugging may be reduced by using a USB isolator. 4. Industrial USB devices: In industrial settings, USB devices like mice, keyboards, and USB-to-serial converters may experience malfunctions or damage due to ground loops or electrical noise. A USB isolator can help reduce failure rates. It can also function as a signal repeater when extending USB cables and helps eliminate ground potential differences between connected devices. 5. Common USB peripherals: Compatible with standard USB peripherals 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, card readers, external hard drives, USB security keys, USB hubs, AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, J-Link, FET430UIF, PICKIT2, XDS100, LPC-Link, ICD2, and USB-to-serial adapters using FT232, CP2102, PL2303, or CH341 chips. Devices not supported: USB wireless network adapters and certain USB 3.0 flash drives.
