Hardware Introduction and Description:
Board size: 63*37mm
Weight: 54g
Scope of application:
⑴. Working environment with strong electricity and strong interference
Some circuits contain strong current and strong interference (such as high voltage, frequency converter, motor drive, etc.) environment. When it is connected to the computer, it must be isolated to ensure the computer and personal safety.
⑵. Noise sensitive areas
The computer is a big noise source. In noise-sensitive areas, we can use this device to isolate the USB interface. Such as high-precision USB data acquisition system, HIFI audio system.
⑶. USB debugging equipment
Such as various USB interface JTAG/SWD emulators, ISP/ASP/IAP/ICP downloaders, etc. When you often fail to connect or simulate abnormalities during debugging, you can use a USB isolator to try to improve.
⑷. Various industrial USB devices
In an industrial environment, USB devices often crash, such as USB mice, keyboards, and USB to serial communication devices. The USB isolator can effectively reduce the crash and damage probability of these devices in an industrial environment. Sometimes it is necessary to extend the USB cable. The USB isolator can act as an excellent USB repeater and can also isolate the ground pressure difference between upstream and downstream devices.
⑸. Other common USB peripherals, such as mouse, keyboard, USB sound card, USB flash drive, printer, digital camera, USB hub (HUB), USB camera.
⑹. Medical equipment
The safety of the human body is the most important and primary consideration, but some medical equipment is connected to the computer through the USB interface. During the process of collecting data or treating the human body, it needs to have direct electrical contact with the human body, and avoid the possibility of passing through the computer. The high voltage conducted by equipment and interface lines to the human body causes electric shock, and electrical isolation of interface lines is one of the important protective measures.
Supported devices:
Full-speed devices: USB flash drives, digital cameras, card readers, mobile hard drives, USB shields, USB hubs, AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, J-Link, FET430UIF, PICKIT2, XDS100, LPC-Link, ICD2 USB to serial port (FT232, CP2102, PL2303, CH341 chips).
