TTL-232R-3V3-WE
Overview
The TTL-232R-3V3-WE is a USB-to-TTL serial UART converter cable incorporating the FT232RQ interface IC. This 1.8-meter cable provides a fast and simple way to connect devices with a 3.3V TTL level serial interface to USB. It terminates in 6 individual wire leads, allowing for direct integration into custom headers or soldered connections.
Why Choose This Part
The cable features an internal EEPROM for storing USB VID, PID, and serial numbers, enabling device customization. It supports a wide range of data transfer rates from 300 baud to 3 Mbaud and handles hardware flow control (RTS/CTS) automatically for reliable data transmission.
Applications
Key Specifications
Getting Started
Installation is straightforward using FTDI's VCP (Virtual COM Port) or D2XX drivers, which are compatible with Windows, Linux, and Mac. The six wire leads (GND, CTS, VCC, TXD, RXD, RTS) can be directly connected to a microcontroller UART port; note that the VCC wire provides 5V from the USB port, while the I/O signals operate at 3.3V logic levels.
