Features: brand new and high quality This is a newly designed product, using PL2303TA chip, PL2303TA provides a convenient solution for connecting an RS232-like full-duplex asynchronous serial device to any Universal Serial Bus (USB) host. PL2303TA is for win XP/VISTA/7/8/8.1 system and can simulate in most operating systems, allowing existing applications based on COM port to be easily ported and perform USB connection function. PL2303TA is capable of higher throughput compared to traditional UART RS232 signal is not required, transfer rate higher than 115200 bps can for even higher performance. The PL2303TA is designed for mobile and embedded solutions, providing a small form factor that can easily fit into any connector and handheld device. With very little power consumption in operating or suspend mode. This product is specially designed for laboratory, product testing, low-cost MCU communication and other applications, with 4 pinouts Red +5V / black GND/ whiteRXD/ greenTXD Specifications: Item: PL2303 TA Data Cable USB for: Single-chip solution upgrade for legacy RS232 devices to USB interface USB to RS232 converter/cable/dongle/data transmission line for medical USB interface USB port for personal infotainment-/media player docking USB interface data transmission line for mobilephone/handheld computer Serial-over-IP Wireless USB-barcode/for smart card reader Positioning system/navigation USB interface Point-of-sale (POS) terminals/printers Computer Docking Station/Port Replicator Industrial/Instrumentation/Automation Control USB Interface USB Modem/Wireless/Zigbee USB Interface USB interface for set-top box (STB)/home for gateway BatteryCharger App USB interface for MCU-based devices Note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand.
