1. Working environment with high electrical interference: Some circuits involve high voltage, inverters, motor drives, and other sources of strong electrical interference. When connecting to a computer in such environments, isolation is required to ensure reliable operation and user safety. 2. Noise-sensitive applications: Computers can generate significant electrical noise. In precision applications such as high-resolution USB data acquisition systems or high-fidelity audio systems, this device can be used to isolate the USB interface and reduce noise interference. 3. USB debugging tools: For USB-based debuggers and programmers such as JTAG/SWD emulators, ISP/ASP/IAP/ICP downloaders, and similar devices, connection issues or abnormal behavior during debugging may be resolved by using a USB isolator to improve signal integrity. 4. Industrial USB devices: In industrial settings, USB devices such as mice, keyboards, USB-to-serial converters, and other communication peripherals are prone to malfunctions. A USB isolator helps reduce the risk of device failure and damage caused by ground loops and electrical transients. It also functions as a USB repeater for cable extension while isolating potential ground voltage differences between connected devices. 5. Common USB peripherals: Supports 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 including 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 with FT232, CP2102, PL2303, CH341 chips.
