Feature:1. The main chip is CP2102, and a virtual serial port is generated after the driver is installed2. USB power supply, the leading interface includes 3.3V (<40mA), 5V, GND, TX, RX, signal pin level is 3.3V, positive logic3. On-board status indicator and transceiver indicator, the status indicator will be on when the driver is installed correctly, and the transceiver indicator will flash during communication.4. Support baud rate from 300bps to 1Mbps5. Communication format support: 1) 5, 6, 7, 8 data bits; 2) support 1, 1.5, 2 stop bits; 3) odd, even, mark, space, none check6. Supported operating systems: windows vista / xp / server 2003/200, MAC0S-X / OS-9, Linux7. The USB head is a male head, which can be directly connected to the USB port of the computer8. Compact design.9. Dimension: 42 mm x 17 mm

Pin description:

G: Ground wire (GND) --- Connect to GND of STC microcontroller

O: Power supply (OUT VCC) --- Connect to VCC of STC microcontroller

R: Receive (RXD) --- Connect P3.1 of STC MCU

T: Send (TXD) --- Connect P3.0 of STC MCU

XD: Sender, generally expressed as its own sender, normal communication must be connected to the RXD of another device.

RXD: The receiving end, generally expressed as its own receiving end, normal communication must be connected to the TXD of another device.

During normal communication, its own TXD is always connected to the RXD of the device!

Self-receiving and spontaneous: RXD is connected to the TXD of other devices during normal communication, so if you want to receive the data sent by yourself, as the name implies, that is, you receive the data sent by yourself, that is, your own TXD is directly connected to RXD, used to test its own transmission and reception Whether it is normal is the fastest and easiest test method. When a problem occurs, the test is first performed to determine whether the product is faulty. Also called loopback test.

Level Logic:

TTL level: Usually the data is expressed in binary, which specifies that + 5V is equivalent to logic "1", and 0V is equivalent to logic "0".

RS232 level: -12V to -3V, equivalent to logic "0", + 3V to + 12V logic level, equivalent to logic "1", negative logic
