USB-to-serial Adapter
A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232, RS-485, RS-422, or TTL-level UART serial data. The older serial RS-423 protocol is rarely used any more, so USB to RS-423 adapters are less common. Uses USB-to-serial RS-232 adapters are often used with consumer, commercial and industrial applications and USB-to-serial RS-485/422 adapters are usually mainly used only with industrial applications. Currently, USB to TTL-level UART converters are used extensively by students and hobbyist as they can be directly interfaced to microcontrollers. Adapters for converting USB to other standard or proprietary protocols also exist; however, these are usually not referred to as a serial adapter. The primary application scenario is to enable USB-based computers to access and communicate with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

FTDI USB SERIAL
Future Technology Devices International Limited, commonly known by its acronym FTDI, is a Scottish privately held fabless semiconductor device company, specialising in Universal Serial Bus (USB) technology. It develops, manufactures, and supports devices and their related cables and software drivers for converting USB signals to and from various protocols, including RS-232/TTL serial (to provide support for legacy devices on modern computers lacking an accessible UART) and inter-chip communication bus protocols (e.g. SPI, I²C, JTAG, or GPIO) to interface with chips like microcontrollers, flash memory, and FPGAs. The company also provides application-specific integrated circuit (ASIC) design services, and consultancy services for product design, specifically in the realm of electronic devices. History FTDI was founded on 13 March 1992 by its current CEO, Fred Dart (whose initials happen to be "FTD"). The company is an indirect descendant of Computer Design Concepts Ltd, a f ...
