TTL-232R-5V
Overview
The TTL-232R-5V is a USB-to-TTL serial UART converter cable that incorporates FTDI FT232RQ IC to handle all USB signaling and protocols. It provides a fast, simple way to connect devices with a 5V TTL level UART interface to USB, appearing as a standard COM port on the host PC.
Why Choose This Part
The cable provides 5V CMOS drive outputs and 5V safe TTL inputs with a high-current VCC output of up to 75mA to power small downstream circuits. It supports fully assisted hardware handshaking (RTS#/CTS#) and features an internal user-writable EEPROM for storing custom USB VID/PID or serial numbers.
Applications
Key Specifications
Getting Started
Installation is plug-and-play using FTDI VCP drivers, which make the cable appear as a virtual COM port in software like PuTTY or Teraterm. The 6-pin 0.1 inch pitch header allows for easy connection to standard breadboards or male pin headers on a PCB.
