## Overview

The DTECH 3ft USB to TTL Serial Cable features a genuine FTDI FT232RL chip enabling stable 3.3V UART communication via USB 2.0. With a 6-pin female header providing full serial signal access and broad OS compatibility, it’s the essential tool for developers and engineers upgrading or debugging embedded systems, microcontrollers, and legacy peripherals.

## Description

3-Foot USB TTL serial adapter built with FTDI FT232RL chip for 3.3V logic level serial communication It is built with FT232r chip that its royalty-free VCP driver allow for communication as a standard COM port and D2XX ‘direct’ drivers provide DLL application programming interface; a great conversion data cord to meet with your needs of debugging, boot-loading, programming, etc. The original FT232 chip is embedded in the USB-A end; 6 way 0.1” header connector with VCC (5V power) and GND (ground), as well as RXD, TXD, RTS and CTS at 3.3V logic level. Applications: Upgrading Legacy Peripherals to USB Interface Microcontroller UART or I/O, FPGA / PLD to USBAs a switching device in driving lamps and relaysReplace MAX232 type level shifters allowing for direct connection of products to PCUsed in processors of mini computers like DEC VAX Industrial Control, USB Software, Hardware Encryption Dongle, printer, video display terminals, Oscilloscope, measurement device, microprocessor, light and remote controller, etc.USB to uart wire, entire USB protocol handled by the electronics in the cable;UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity;Data transfer rates from 300 to 3M baud rate at TTL levels;Internal EEPROM with users writable area; Supply voltage comes from USB bus, no external supply required; UHCI / OHCI / EHCI host controller compatible Interfaces: USB 2.0 type A Male Port ; 3 pin Female Socket flying leads Supports Windows 2008, XP, Vista , CE 4.2, 5.0 and 6.0, Windows 11, 7, 8, 8.1, 10; Mac, LinuxNOTE: If any installation or usage issues, please email us or you may download a driver and usage guide on FT232 chip official website What’s Included 1x Type A male USB to Serial TTL Level Converter Cable 3 ft 1x Manual

Review: It works! - Works as described, color coding on the wires isn't intuitive, make sure you read the included instructions
Review: Deceived and disappointed - It did not meet my expectations . The USB end, housing, is not secure at all. The RS232 end was not as it was described. The JST connector was smaller and thinner than expected. I a not sure if the pin layout is the same end to end.

### ⭐ Deceived and disappointed

It did not meet my expectations . The USB end, housing, is not secure at all. The RS232 end was not as it was described. The JST connector was smaller and thinner than expected. I a not sure if the pin layout is the same end to end.

### ⭐⭐⭐⭐⭐ Works perfectly.
*by D***. on October 2, 2024*

Does what it says on the tin... if you have an embedded device with a 3.3V UART coming to 100-mil headers, this cable will connect to it. Easy.
