Optically isolated USB to TTL serial port (ie UART, COM port)
The classic and reliable photoelectric isolation circuit greatly improves the safety and anti-interference performance of serial communication debugging. It is very suitable for high voltage and strong pulse industrial occasions. The module integrates an isolated power supply without external power supply, and supports baud rates up to 921600bps. , Powerful performance and easy to use.
main feature
● The original CH340 main control provides Windows/Lniux/Mac 32/64 bit operating system driver, and the native serial port program does not need any modification.
●Original imported high-speed optocoupler, good waveform, maximum speed of 921600bps (8 times of 115200)
●Complete electrical isolation (including power supply and GND), 1500V withstand voltage, fully protect the computer and personal safety.
●There is no electrical connection between the USB terminal and the serial port, which fully guarantees that the computer will not be damaged due to external short circuit, impact, etc., and will not crash due to strong pulses or interference.
●The PCB is slotted and the separation distance is more than 3mm to ensure enough distance to avoid creepage.
●Original Jinshengyang lengthened isolated power supply, with large spacing and high voltage resistance.
●The output power VCC and signal level can be switched to 5V/3.3V, which is suitable for systems with different voltages.
●Integrated isolated power supply, USB plug and play, no separate power supply, and can provide 100mA current output to the outside.
●The signal line integrates protective diodes to improve shock resistance.
●Integrated power supply, sending and receiving three LED indicators, convenient to observe the communication status.
●TX integrated reverse diode, provides TX-D with open-drain output, which is convenient for programming the MCU program (TX without reverse diode will supply power to the MCU and cause incomplete power failure and download failure)
