Il est reconnu directement sous Windows 10 & 11. Il est fourni avec tous les câblages nécessaires : 1 câble USB et 4 câbles pour les ports UART. La connectique des câbles UART sont d'une part (côté du convertisseur USB2UART)) un bloc de 6 câbles avec détrompeur et d'autre part (côté à connecter sur carte électronique) 6 connecteurs individuels (de type Dupont). La sélection 5V/3.3V est très utile si vous utilisez le convertisseur sur un système ne supportant pas une tension supérieure à 3.3V. Bon produit dans l'ensemble Review: Super - Funktioniert wie es soll. ## Features - Extending USB to 4CH TTL (UART) with hardware flow control, allows concurrent and independent communication for each channel Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, - Onboard IO protection circuit for surge suppress and ESD protection, safe and stable communication Onboard TTL serial port 3.3V and 5V voltage level switch, allows selecting TTL level. - Aluminium alloy enclosure with oxidation dull-polish surface, CNC process opening, solid and durable, well-crafted Quality USB-B connector, and IDC connector with fool-proof design. - Onboard Resettable Fuse And Protection Diode, Provides Over-Current/Over-Voltage Proof, Improves Shock Resistance; Onboard IO Protection Circuit For Surge Suppress And ESD Protection, Safe And Stable Communication. - Suitable For Industrial/Office Conditions With Strict Requirements For Operating Environment And Devices. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09SZ33J9H | | Best Sellers Rank | 116,229 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 281 in Barebone PCs | | Brand | Waveshare | | Brand Name | Waveshare | | Colour | Black | | Compatible Devices | PC, Laptops, Printers | | Compatible devices | PC, Laptops, Printers | | Connector Type | USB-B, 6PIN fool-proof header | | Connector type | USB-B, 6PIN fool-proof header | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 20 Reviews | | Finish type | Dull-polish | | Input Voltage | 5 Volts | | Item Weight | 0.2 Kilograms | | Item weight | 0.2 Kilograms | | Manufacturer | Waveshare | | Manufacturer Part Number | USB TO 4CH TTL | | Model Number | USB TO 4CH TTL | | Nominal Power | 10 Watts | | Number of Items | 1 | | Number of Ports | 4 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Product Finish Type | Dull-polish | | Unit Count | 1.0 count | | Warranty Type | Limited | ## Images ![Waveshare Industrial USB to 4CH TTL Converter USB to UART with Multi Protection Circuits Multi Systems Support - Image 1](https://m.media-amazon.com/images/I/715uYuCo9VL.jpg) ![Waveshare Industrial USB to 4CH TTL Converter USB to UART with Multi Protection Circuits Multi Systems Support - Image 2](https://m.media-amazon.com/images/I/61LwfYmF3yL.jpg) ![Waveshare Industrial USB to 4CH TTL Converter USB to UART with Multi Protection Circuits Multi Systems Support - Image 3](https://m.media-amazon.com/images/I/615mDE+vaZL.jpg) ![Waveshare Industrial USB to 4CH TTL Converter USB to UART with Multi Protection Circuits Multi Systems Support - Image 4](https://m.media-amazon.com/images/I/61KNY++AJbL.jpg) ![Waveshare Industrial USB to 4CH TTL Converter USB to UART with Multi Protection Circuits Multi Systems Support - Image 5](https://m.media-amazon.com/images/I/61Nwwb-2O0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bon produit de bonne qualité *by M***C on 24 March 2024* Le convertisseur USB vers 4 ports TTL est de bonne qualité et de finition impeccable.
