FTDI TTL-232R-3V3-PCB USB to TTL Serial Converter Module
FTDI USB to TTL serial converter PCB with FT232RQ, 3V3 output, up to 3Mbaud, USB powered. Ideal for industrial, wireless, sensing.
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.
