FTDI DB9 USB to Digital Modules

FTDI DB9 USB to Digital Modules

FTDI's DB9 USB to Digital Modules provide a simple and fast method of migrating existing DB9 based connector UART interfaces to USB 2.0. In some cases these DB9 USB to Digital Modules can reduce system costs by removing an RS232 level shifter from a design. The FTDI DB9 USB to Digital Modules feature a USB 2.0 mini-B connector within a module which fits a standard 9-pin DB9 connector footprint. The DB9 USB to Digital Modules are ideal for legacy applications which feature UART DB9 based connectors, these modules provide a method of extending the life-cycle of these products by converting them to USB 2.0 connectivity, with minimal redesign.

Features
  • Adds one USB serial port by connecting to the RS232 DB9 footprint of a device
  • Easy placement for an standard Male and Female RS232 DB9 footprint of a device
