Simple to install. Hardly no setup needed. Works great. Review: Worked great - Genuine PL2303GC & Windows 11 - Some reviews of this product complained about this DTech USB to TTL Serial cable not working with Windows 11 and/or getting a counterfeit device. I can't really verify whether mine was counterfeit but it showed up as a "Prolific PL2303GC USB Serial COM Port" in Device Manager on Windows 11 immediately, without having to hunt for drivers. I configured Putty to connect via serial, keyed in the COM Port that Device Manager defined the adapter as, connected the ground/TX/RX leads to the appropriate place on the Linksys EA6350v2's board, and gave the router power. Everything worked perfectly and allowed me to do the necessary things over serial to flash FreshTomato onto the router's flash memory. Included with the cable was a small pamphlet serving as documentation as well as a pinout/schematic of what's inside the slightly oversized USB connector. ## Features - 6 ft USB to TTL serial adapter (with 4 pin 0.1” pitch female header socket) connects devices with 3.3 V logic level UART signals interface to a laptop via USB port - A genuine PL2303TA chip module is housed in USB 2.0 type A male terminal for wider compatibility and supports reliable data transfer rates - 6 feet USB to TTL serial cable 3V3 (4 way output flying leads ) provides access to UART (transmit) Tx, (receive) Rx, VCC (5V) and GND - PL2303 Prolific chipset on the PCB board has configurable internal EEPROM and UART signals can be individually inverted by configuring the EEPROM - 4 pin 3.3V USB to TTL converter cord Compatible with Windows 10, 8, 8.1, 7 (32, 64-bit), 2008/XP/Vista/CE; ideal USB 2.0 debug cord for Vendor ID re-write, router, GPS, set top box, transmitter, flash firmware on hard drive, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07R8BQYW1 | | Best Sellers Rank | #30 in Serial Adapters #3,612 in Computer Cables & Interconnects | | Brand | DTECH | | Brand Name | DTECH | | Cable Type | USB | | Color | 4 pin 3.3V | | Compatible Devices | computer, Laptop, calculator, MBP, router, microphone, industrial controls, test equipment and instrumentation, consumer electronics, synthesizers, machine tool numerical controls, printers and video display terminals Compatible Devices computer, Laptop, calculator, MBP, router, microphone, industrial controls, test equipment and instrumentation, consumer electronics, synthesizers, machine tool numerical controls, printers and video display terminals See more | | Connectivity Technology | USB | | Connector Gender | Male-to-Female | | Connector Type | 4 pin TTL, USB Type A | | Customer Reviews | 4.3 out of 5 stars 212 Reviews | | Data Transfer Rate | 3 megabits_per_second | | Indoor Outdoor Usage | Indoor | | Item Shape | Round | | Item Weight | 0.27 g | | Manufacturer | Guangzhou DTECH Electronics Technology Co.,Ltd | | Maximum Voltage | 3.3 volts | | Model | DT-6553 | | Model Name | DT-6553 | | Number of Items | 1 | | Number of Pins | 4 | | Other Special Features of the Product | Data Transfer, PL2303 chip | | Part Number | DT-6553 | | Recommended Uses For Product | Indoor | | Special Feature | Data Transfer, PL2303 chip | | Specification Met | ISO | | UPC | 714131653102 | | Unit Count | 1 Count | | Warranty Description | 1 Year | ## Product Details - **Brand:** DTECH - **Cable Type:** USB - **Connector Type:** 4 pin TTL, USB Type A - **Special Feature:** Data Transfer, PL2303 chip ## Images ![USB to TTL Serial 3.3V Adapter Cable TX RX Signal 4 Pin 0.1 inch Pitch Female Socket PL2303 Prolific Chip Windows 10 8 7 XP Vista (6ft, Black) - Image 1](https://m.media-amazon.com/images/I/51VQwX7E7aL.jpg) ## Questions & Answers **Q: does this device work with linux 5.4?** A: Yes, it works great on Linux.

Only downside is I had to figure out what cable was for what port, as the cables are not easily identified, and the instructions had them wrong. Eventually, I figure out and got my router back up. ## Frequently Bought Together - DTech USB to TTL Serial 3.3V Adapter Cable TX RX Signal 4 Pin 0.1 inch Pitch Female Socket PL2303 Prolific Chip Windows 10 8 7 XP Vista (6ft, Black) - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - DSD TECH SH-U09C5 USB to TTL UART Converter Cable with FTDI Chip Support 5V 3.3V 2.5V 1.8V TTL --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/138973217-usb-to-ttl-serial-3-3v-adapter-cable-tx-rx](https://www.desertcart.in/products/138973217-usb-to-ttl-serial-3-3v-adapter-cable-tx-rx) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-09-25*
