FTDI TTL-232R-3V3-PCB USB to TTL Serial Converter Module

The FTDI TTL-232R-3V3-PCB is a USB to TTL serial UART converter PCB, incorporating the FT232RQ USB to Serial UART interface IC device, which handles all USB signalling and protocols. This PCB offers a fast and simple way to connect devices with a TTL level serial interface to USB, making it ideal for a wide range of applications.

The board is USB powered and USB 2.0 full speed compatible, with support for data transfer rates up to 3Mbaud. It includes a USB type A connector and an internal electronic circuit board utilising the FT232R chip. The PCB also supports the FTDIChip-ID feature, with a unique USB serial number programmed into the FT232R, which can be used to create security or password protected file transfer access.

Key Features

• On board FT232RQ provides single chip USB to asynchronous serial data transfer interface
• Entire USB protocol handled by the electronics on the PCB
• Connect directly to a microcontroller UART or I/O pins
• Fully assisted hardware or X-On / X-Off software handshaking
• Internal EEPROM with user writeable area
• Support for FT232R FTDIChip-ID feature for improved security
• PCB is USB powered, no external supply required
• 3.3V output allows external logic to be powered from the USB port
• Low USB bandwidth consumption
• UHCI / OHCI / EHCI host controller compatible

Drivers

Requires USB drivers, which are used to make the FT232R on the PCB appear as a VCP, allowing communication via a standard PC serial emulation port. The D2XX driver can also be used with application software to directly access the FT232R through a DLL.

Applications

This module is suitable for communications, networking, industrial, wireless, sensing, and instrumentation applications.
