Magnetic isolation usb to ttl serial port
Ft232rl magnetic isolation usb to ttl serial interface(I.e. uart/com mouth)Module, main control using ftdi usb chip ft232rl, adi company digital isolation device adum3201, gold shengyang power isolation module, with 1000v dc isolation voltage and up to 1mbps reliable communication rate.Usb side and ttl output side are completely isolated, fully guarantee computer security, effectively reduce interference.
Characteristics
Ft 232rl master control, industry reputation of excellent usb chips, industrial applications stable selection. Adi magnetic isolation chip adum 3201, fast, good waveform, power consumption is significantly lower than photoelectric isolation. Board-mounted large space separation power supply, no external power supply, just insert usb interface can be used. Increase isolation gap, pcb slot, better avoid climbing electricity, improve safety performance. Integrated protection diodes to improve protection capability. Usb-a male interface, no connection line, plug directly into the computer usb port can be used. The communication level can be easily switched to 5v or 3.3v via the jumper cap. Vcc output voltage can output 5v/3.3 v, communication level and vcc voltage can be the same or different. Tx leads to independent tx-d (leakage output) by reverse diode, which is convenient to connect to record stc single chip. Board power supply, send, receive three led indicator lights. Typical applications
Isolation usb to ttl serial port communication and debugging under high voltage hazard Upgrade router, top box, etc. external firmware Record (download) single chip computer program High speed usb uart communication (limit to 2mbps) Put it in the product to improve communication reliability Our shop is a trader, and no engineer is not supportive of technical problems
Frequently asked questions
Which environments require isolation of usb interfaces
Usb interface is already one of the most common interfaces for electronic engineers, practitioners and daily work. As the computer industry becomes more competitive and the price of products becomes lower, most businesses are forced to simplify and save on the main board interface protection.Usb interface not only often contact the human body, external contact, but also often supply external equipment.External strong power, strong interference to the usb port caused great pressure.This has led to early strikes on many computers' usb interfaces and even damage to the main board.
