Product Details

USB to Serial DE9 Module

Designed to replace an existing DE9 connector, (male or female) RS-232/TTL UART connection with a drop-in USB replacement connection.

Miniaturised modules which closely resemble a DE9 connector for PCB mounting
USB mini-B socket connector
The modules contain a USB-Serial bridge IC and all necessary electronics to convert between USB and RS-232/UART signals

FTDI Chip Db9-USB To UART Converter Module

The FTDI Chip DB9-USB to UART converter module is used to upgrade an RS232 port to an active USB port without the need to redesign the PCB. The family consist of 6 modules, 2 of them operate at RS232 voltage levels while 4 of them operate at digital voltage level (a choice of 5V or 3.3V). Each of these is available to replace a male DB9. This active connector contains all the USB to UART (and vice versa) conversion electronics and is designed to fit directly into the same PCB footprint as a PC compatible UART DB9 connector.

Features and Benefits

• Easy placement for an standard male RS232 DB9 footprint of a device
• A selection of RS232, 3.3V or 5V UART signal levels
• Works with USB 1.1 & 2.0 Host and Hub ports
• Industry Standard FTDI chip set & device drivers for maximum compatibility
• Microsoft Windows® WHQL-certified, Mac OS X, Linux and Windows CE device drivers
• Installs as a standard Windows COM port
• Has 128 byte transmit buffer and 256 byte receive buffer
• Powered by USB port, no external power adapter required
• Serial port speed up to 1Mbps
• Operating temperature ranges between -40°C and 85°C


• ANSI/ESD S20.20:2014
• BS EN 61340-5-1:2007
