Magnetically isolated USB to TTL serial port
FT232RL with magnetic isolation USB to TTL serial interface (ie UART/COM port) module, the main control uses FTDI USB chip FT232RL, uses ADI’s digital isolator ADUM3201, Jinshengyang power isolation module, has 1000V DC isolation voltage and up to 1Mbps reliability Communication rate. The USB side and the TTL output side are completely isolated, which fully guarantees the safety of the computer and effectively reduces interference.
FT232RL main control, USB chip with excellent industry reputation, stable choice for industrial applications.
ADI magnetic isolation chip ADUM3201 has fast speed, good waveform, and power consumption is significantly lower than photoelectric isolation.
The onboard large-spacing isolated power supply does not require 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 capability.
USB-A male interface, no need to connect the 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.
The VCC output voltage can output 5V/3.3V, and the communication level and VCC voltage can be the same or different.
TX leads to an independent TX-D (open-drain output) through the reverse diode, which is convenient for connecting and programming STC microcontroller.
On-board power supply, sending and receiving three LED indicators.
