I had no issues getting it up and running. Because of the terminal block connections, it's industrially rugged and makes it safe on your bench, no pulling off headers or individual wires on a breadboard. ## Features - Adopt original FT232RNL chip, fast communicating, stable and reliable, better compatibility. Supports multiple communication interface conversion: USB to RS232, USB to RS485, USB to RS422, USB to TTL - Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption - Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance - Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering with each other. Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch - 3 LEDs for indicating the power and transceiver status. High quality USB-B and RS232 connectors, smoothly plug/pull. Industrial grade metal case, supports wall-mount and rail-mount installations, solid and beautiful, easy to install ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BTYKS8LK | | Best Sellers Rank | #149 in Serial Adapters | | Brand | waveshare | | Color | USB TO RS232/485/422/TTL | | Compatible Devices | Television | | Connector Type | USB-B | | Current Rating | 5 Amps | | Customer Reviews | 4.8 out of 5 stars 46 Reviews | | External Testing Certification | Não aplicável | | Finish | Metallic | | Finish Type | Metallic | | Input Voltage | 5 Volts | | Item Weight | 0.05 Kilograms | | Manufacturer | Waveshare | | Mfr Part Number | USB TO RS232/485/422/TTL | | Model Number | RS3059" or "RB-Wav-431 | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Unit Count | 1.0 Count | | Warranty Type | Limited | ## Product Details - **Brand:** waveshare - **CPU Socket:** DIP - **Chipset Type:** FT232RL - **Compatible Devices:** Television - **Compatible Processors:** Intel Celeron - **Main Power Connector Type:** 24-Pin - **Memory Storage Capacity:** 8 GB - **Model Name:** FT232RNL - **Platform:** Android, Linux, Windows - **RAM Memory Technology:** DDR4 ## Images ![waveshare FT232RNL USB to RS232/485/422/TTL Interface Converter, Industrial Isolation - Image 1](https://m.media-amazon.com/images/I/61ejBKFtpEL.jpg) ![waveshare FT232RNL USB to RS232/485/422/TTL Interface Converter, Industrial Isolation - Image 2](https://m.media-amazon.com/images/I/61jTuQdjwXL.jpg) ![waveshare FT232RNL USB to RS232/485/422/TTL Interface Converter, Industrial Isolation - Image 3](https://m.media-amazon.com/images/I/61KHg2i0ecL.jpg) ![waveshare FT232RNL USB to RS232/485/422/TTL Interface Converter, Industrial Isolation - Image 4](https://m.media-amazon.com/images/I/81ewCOBPV5L.jpg) ![waveshare FT232RNL USB to RS232/485/422/TTL Interface Converter, Industrial Isolation - Image 5](https://m.media-amazon.com/images/I/81fSwzv3B2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by R***S on January 7, 2026* Works great ### ⭐⭐⭐⭐⭐ USB to Serial converter *by M***E on January 27, 2025* This unit is very well made. I had no issues getting it up and running. Because of the terminal block connections, it's industrially rugged and makes it safe on your bench, no pulling off headers or individual wires on a breadboard. ### ⭐⭐⭐⭐⭐ outstanding device *by L***H on November 23, 2024* works like a charm. designed and built well. the TTL port is very convenient for microcontroller comms. RS-232 port operates very smoothy and is not jerky like cheaper USB to serial converters. I use the device with OpenBSD and FreeBSD. Also works with Linux. ## Frequently Bought Together - waveshare FT232RNL USB to RS232/485/422/TTL Interface Converter, Industrial Isolation - DTECH USB to RS422 RS485 Serial Port Converter Adapter Cable with FTDI Chip Supports Windows 11 10 8 7 XP Mac -1.5 Feet - Waveshare USB to RS485 Converter with Protection Circuits, Compatible with TVs --- ## 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.it/products/530753073-waveshare-ft232rnl-usb-to-rs232-485-422-ttl-interface-converter](https://www.desertcart.it/products/530753073-waveshare-ft232rnl-usb-to-rs232-485-422-ttl-interface-converter) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-15*
