FTDI Isolated USB to UART TTL, USB to Serial Port TTL 5V3.3V2.5V1.8V Optically Isolated Magnetic Isolation Adapter
This is a magnetically isolated USB to TTL serial interface (ie UART/COM port), the main chip uses FTDI FT232RL, originally designed by DBS Technology, with 1000V DC isolation voltage and reliable communication speed up to 3Mbps, USB The side and the TTL side are completely isolated, which fully guarantees computer security and effectively reduces interference.
Model Description
●5V/3.3V (dual level): The power supply voltage and signal level can be switched to 5V/3.3V, and the power supply voltage and signal are different.
●5V/3.3V/2.5V/1.8V (four-level): The power supply voltage and signal level can be switched to 5V/3.3V/2.5V/1.8V, and the power supply voltage and signal are different.
This module is delivered with 20cm DuPont 4P cable freely.
Main Feature
●FT232RL main control, the industry's excellent USB to serial chip, a stable choice for industrial applications.
●The latest generation of ADI magnetic isolation chip ADU3201 has fast speed, high waveform, and power consumption is significantly lower than photoelectric isolation.
● On-board large-spacing isolated power supply, no need for external power supply, just plug in the USB interface to use.
● Increase the isolation gap and slot the PCB to better avoid creepage and improve safety performance.
● Integrated protection diode to improve protection ability.
● USB-A male connector, no need to connect cable, directly plug into the computer USB port to use.
● The communication level can be conveniently switched to 5V or 3.3V through the jumper cap (four-level models support 2.5V/1.8V).
● VCC can output voltage 5V or 3.3V (four-level model supports 2.5V/1.8V). , The communication level and VCC can be the same or different.
● TX leads to TX-D (open-drain output) through the reverse diode, which is convenient for programming STC single-chip microcomputer, and avoids incomplete programming failure after power failure.
● On-board power supply, sending and receiving three LED indicators, observe the communication status at any time (dedicated IO driver, not connected in parallel to the signal line, does not affect communication).
Application
● Isolation USB to TTL serial communication and debugging equipment under high voltage danger.
● Upgrade the peripheral firmware such as routers and set-top boxes.
● Burn (download) MCU program
● High-speed USB UART communication (up to 2Mbps)
● Built into the product to improve communication reliability
