Optically isolated USB to TTL serial port (i. e. UART, COM port)
The product model on this page: MCS-86C
MCS-86C is an optically isolated USB to UART serial port, using CH340 chip, classic and reliable optocoupler isolation circuit, with 1500V isolation voltage and up to 921600bps communication rate, providing 5V/3.3V two levels, very suitable for high voltage, strong Serial communication and debugging under interference conditions fully guarantee computer safety.
This module is delivered with a 20cm Dupont cable 4P, if you need a USB extension cable,
Please buy together!
Main feature
● Original CH340 main control, providing Windows/Lniux/Mac 32/64 bit operating system driver, 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 circuits, impacts, 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 sufficient distance to avoid creepage.
●Original Jinshengyang extended isolated power supply, with large spacing and high voltage resistance.
●The output power VCC and signal level can be switched to 5V/3.3V, adapting to 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 the impact resistance.
●Integrated three LED indicators for power supply, sending and receiving, convenient to observe the communication status.
●TX integrates reverse diodes and provides TX-D with open-drain output, which is convenient for programming the MCU program (TX without reverse diodes will supply power to the MCU and cause incomplete power failure and download failure)
Pin function
The pins that must be connected for normal communication:
●Level selection pin: used to select the signal and power VCC pin level, it must be connected to one of 5V or 3.3V.
●TX: Serial data transmission pin (refers to the module’s own data outflow→, corresponding to the RX. data reception of the external device. )
●RX: Serial data receiving pin (refers to the module’s own data input ←, corresponding to the external device’s TX. data transmission. )
●GND: power ground (GND must be connected and must not be connected wrongly, otherwise the device or serial port module may be damaged)
The following pins are not necessary for communication, you can decide whether to connect according to your needs
●VCC: power output (the voltage is determined by the level selection jumper cap, the maximum load should not exceed 150mA, and it is recommended to be below 100mA)
●TX-D: TX through the reverse diode, that is, the TX signal with open drain output, which can only output low level and needs to be pulled high externally. When the STC microcontroller downloads the program, use TX-D instead of TX and connect to the P30 pin of the MCU.
●5V: 5V power output (from USB, the maximum load should not exceed 150mA, recommended below 100mA).
●3.3V: 3.3V power output (from LDO, the maximum load should not exceed 150mA, and it is recommended to be below 100mA).
Prompt
● This module can support the signal pin and power pin to switch to 5V/3.3V at the same time (using VCC for external power supply, the signal pin and VCC have the same level), and can also support the signal and power to use different levels (using 5V or 3.3 V pin provides external power supply).
● In the factory test, the default level is 3.3V. TX/RX are directly connected, just remove it when using.
● Baud rate: 50, 75, 100, 110, 134.5, 150, 300, 600, 900, 1200, 1800, 2400, 3600, 4800, 9600, 14400, 19200, 28800, 33600, 38400, 56000, 57600, 76800, 115200, 128000, 153600, 230400, 460800, 921600, 1500000, 2000000 (other than non-standard rates are not supported)
Precautions
● There are some isolated serial ports on the market that require an external power supply. This module integrates an isolated power supply, no external connection is required, and USB plug and play.
● This module is TTL level (5V/3.3V) and cannot be connected to RS-232 level (+-5V to +-15V). Please confirm the level of your device before use.
