Description: Stable and reliable chipset CP2102 USB specification 2.0 compliant with full-speed 12Mbps. Standard USB type A male and TTL 5pin connector. 5pins for 3.3V,TXD,RXD,GND 5V Byte receive buffer; 640 byte transmit buffer. All handshaking and modem interface signals. USB suspend states supported via SUSPEND pins. Hardware or X-On/X-Off handshaking supported. Specification: Event character support Line break transmission. Supports Windows 98SE, 2003, XP, Vista, Window7, Mac OSX , Linux 2.6.x and 2.4.36 Temperature Range: -40?to +85? Baud rates: 300 bps to 1.5 Mbps Size: 45 x 19 x 5 mm / 1.77" x 0.74" x 0.19" (LxWxH) Pins length: 7mm / 0.27" Cable length: 20.5cm / 8.07" Package Includes: 1x USB 2.0 To TTL UART STC Module Note: TXD: Transmit(tx) Data, one device's TXD need to be connected with another device's RXD during data transmission. RXD: Receive(rx) Data, one device's RXD need to be connected with another device's TXD during data transmission. When problem occurs, connecting device's TXD directly to its RXD is the fastest and easiest way to find out if the product itself went wrong. Also known as loop test. Level logic: TTL level: usually using binary, specified that + 5V equivalent to logic "1", 0V equivalent to logic "0", called TTL signal system. Positive logic RS232 level: using -12V to -3V, equivalent to logic "0", +3 V to +12 V logic level, equivalent to logic "1". Negative logic Instruction: The main chip is CP2102, install the driver to generate virtual serial port Lead interface including 3.3V (
