1X(FT232 module CP2102 Module USB to TTL USB 2.0 Serial Module UART STC Dow I6J7

1X(Chip: The main chip CP2102, generate a virtual serial port after installing the driver.Baud Rate: Supporting 300bps ~ 1Mbps
Communication Format: supporting 5, 6, 7, 8 data bits ; 1, 1.5, 2 stop bits ; odd, even, mark, space, none verification.
Support Operating System: windows vista / xp / server 2003/200, Mac OS-X/OS-9, Linux
USB to take power, leads to the interface includes 3.3V( Less than 40mA),5V, GND, TX, RX, the signal pin level is 3.3V, positive logic. Onboard status indicator lights transceiver, install the correct drivers status indicator lit, when the communication transceiver indicator flashes , the higher the intensity , the lower the baud rate
Male USB head, can be directly connected to the computer USB port. SMT chip components for the production process , quality and stability
Tips ( very important ):
TXD: the sender, usually expressed as its sender , the normal communication must be connected to another device RXD.
RXD: the receive side, generally expressed as the receiving end of their normal communication to another device connected to TXD.
When normal communication TXD never received their equipment RXD!
Collected spontaneously: normal communication other devices connected RXD TXD, so if you want to receive data sent their name suggests, it is their own transmitted data received , which is connected directly to its own TXD RXD, used to send and receive the test itself is normal, is the quickest and easiest way to test if a problem occurs first do the test to determine whether a product failure. Also known as the loopback test.
Level logic:
TTL level: typically binary data representation , provides 5 V equivalent to the logic "1", 0V is equivalent to logic "0" , is called a TTL signal system is the positive logic
RS232 level: the -12V to -3V, equivalent to logic "0", 3 V to 12 V logic)
