5 PCS CP2102 Module STC Download Cable USB 2.0 to TTL 6PIN Serial Converter Super Brush Line Upgrade For Arduino

Product Description TXD: the sending end, generally expressed as its own transmitter, the normal communication must be connected to another device RXD. RXD: the receiving end, generally expressed as its own receiving end, the normal communication must be connected to another device TXD. Normal communication when the TXD itself is always connected to the device RXD! Since the resumption of spontaneous: normal communication RXD connected with other devices on the TXD, so if to receive send their data as the name suggests is yourself to receive send their data, namely its TXD directly connected to the RXD pin used to test the sending and receiving is normal or not is the fastest the most simple test method, when there was a problem first do the test to determine whether or not the fault of the products. Also known as the loopback test. Level logic: TTL level: the data is usually represented by binary, +5V equivalent to the logic "1", 0V equivalent to the logic "0", called the TTL signal system, is the positive logic RS232 level: the use of -12V to -3V, equivalent to the logic "0", +3V to +12V logic level, equivalent to the logic "1", is a negative logic Product description: 1, the main chip for the CP2102, after the installation of virtual serial port 2, USB power, extraction interface, including 3.3V (<40mA), 5V, GND, TX, RX, signal pin level is 3.3V, positive logic 3, Board a load state indicating lamp, a transceiver indicating lamp, properly installed driver state indicator light, transceiver indicating lamp in communication will flash, baud rate higher brightness is low 4, support from the 300bps~1Mbps baud rate 5, communication format support: 1) 5, 6, 7, 8 bit data bit; 2) support 1, 1.5, 2 stop bit; 3) odd, even, mark, space, none check 6, support the operating system: vista/xp/server 2003/200 windows, OS-X/OS-9 Mac, Linux 7, USB head for the public head, can be directly connected to the computer USB port 8, the patch components for the production of SMT technology, quality and stability 9, does not contain the USB head volume: (mm) The purchase of the product includes the following parts: 1. welding test a good module 2. 20 cm long 4P DuPont line
