UMFT234XD Datasheet Version 1.1 Document Reference No.: FT 000801 Clearance No.: FTDI 327 Future Technology Devices International Datasheet UMFT234XD Breakout Modules UMFT234XD is a USB to UART breakout module 1 Introduction The UMFT234XD breakout module utilizes FTDIs FT234XD IC to convert USB to UART. 1.1 Features The UMFT234XD is a breakout board that converts USB2.0 Full-Speed to UART. These modules do not have a USB connector, instead, the modules plug directly into the USB host connector and the pads of the PCB makes electrical contact with the electrical contacts of the USB connector. The UART interface operates at +3.3V voltage levels, however all I/Os are 5V tolerant. 1.2 Ordering Information Module Interface Features UMFT234XD-01 UART USB to UART with four control bus lines, 3.3V power out limited to 50mA and 5V with as safety fuse. UART signals available via 8 pin female connector. UMFT234XD-NC UART USB to UART with four control bus lines, 3.3V power out limited to 50mA and 5V with as safety fuse. UART signals available via 8 pads on the PCB. UMFT234XD-WE UART USB to UART with four control bus lines, 3.3V power out limited to 50mA and 5V with as safety fuse. UART signals available via 8, 6 flying leads connected to the PCB pads. 2 Driver Support Royalty-Free VIRTUAL COM PORT (VCP): Royalty-Free D2XX Direct Drivers: Windows 8 32,64-bit Windows 8 32,64-bit Windows 7 32,64-bit Windows 7 32,64-bit Windows Vista Windows Vista Windows XP 32,64-bit Windows XP 32,64-bit Windows XP Embedded Windows XP Embedded Windows CE.NET 4.2 , 5.0 and 6.0 Windows CE.NET 4.2, 5.0 and 6.0 MAC OS OS-X MAC OS OS-X Linux 3.0 and greater Linux 3.0 and greater Android Android The drivers listed above are all available to download for free from www.ftdichip.com.
