Voltage jumper is a major benefit. - I'm here to buy a second because the first is so awesome. Ran into a situation today where I wanted to take my MCU out of the loop to see exactly what the computer was sending. Which means I need one for my transmit computer and my receive computer. This is so easy to use. and the voltage selection jumper is just genius. My preferred dev MCU is the latest Teensy, which is 3.3 V. Sometimes an Arduino is a better pick for the project, though, so I need 5v capability. No level shifters required here--just set the jumper. I love it. Review: Look no further! AWESOME USB to UART adapter - I have been using this adapter for a few years now for all my ESPHome projects and absolutely love it! I've made custom cables I use for different types of devices I use it with so it is always ready to go. The fact it has voltage selection is super convenient as some of the devices in the ESP32 world need 5V and other 3.3V. Also, I use one of the pins (GND) for the cases in which you have to ground something to flash it. The fact it has a case is a MAJOR benefit compared to most other alternatives... who knows how many I would have shorted to date without a case! Absolutely recommend it!! ## Features - Support 4 kinds of TTL levels:This is a versatile USB to TTL converter. It is powerful enough to handle almost all TTL level communications. It is compatible with 5V, 3.3V, 2.5V, 1.8V TTL levels. - FTDI FT232RNL Chip:Built-in original FTDI FT232RNL Chip.Industrial grade, Compatible with Windows 7, 8, 10, 11, Linux, MacOS - Protective case:Comes with a protective case, this transparent protective case can effectively prevent static interference from the hand and prevent accidental short circuit - It provides access not only to UART TX,RX, RTS, CTS, VCC and GND pins,but also provides access to DSR,RI,DCD,DTR,RESET pins - What You Get: SH-U09C5 USB to UART Adatper, 6PIN Cable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WX2DSVB | | Best Sellers Rank | #9 in Serial Adapters | | Brand | DSD TECH | | Color | Multi-Coloured | | Compatible Devices | Laptop | | Connector Type | USB | | Customer Reviews | 4.8 out of 5 stars 932 Reviews | | Finish | Plastic | | Input Voltage | 5 volts | | Item Dimensions | 1.5 x 0.4 x 0.15 inches | | Item Weight | 5.67 g | | Item dimensions L x W x H | 1.5 x 0.4 x 0.15 inches | | Manufacturer | DSD TECH | | Mfr Part Number | DS-SH-U09C5 | | Model Number | SH-U09C5 | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | [Microcontrollers, Embedded Systems, TTL Devices, Computers, Laptop] | | UPC | 734678383270 | | Unit Count | 1 Count | | Warranty Description | 1 year warranty | | Warranty Type | Limited | ## Product Details - **Color:** Multi-Coloured - **Compatible Devices:** Laptop - **Connector Type:** USB - **Item dimensions L x W x H:** 1.5 x 0.4 x 0.15 inches - **Specific Uses For Product:** [Microcontrollers, Embedded Systems, TTL Devices, Computers, Laptop] ## Images ![Model:SH-U09C5 - Image 1](https://m.media-amazon.com/images/I/71TnwREtkTL.jpg) ## Questions & Answers **Q: Does it come with a 4 pin cable or 6 pin cable?** A: Mine came with a 6 pin rainbow cable **Q: What baud rates are supported?** A: Common baud rates are supported such as 2400, 4800, 115200.

Used to modulate a DTR pin from a USB port with excellent results - solved a problem I'd been working with for WEEKS! Not mentioned was that an approximately 11-inch interface cable is also supplied, and the unit came with TX and RX pins shorted with a jumpter to make it easy to see the interface was working. I will definitely recommend this product to others! ## Frequently Bought Together - DSD TECH SH-U09C5 USB to TTL UART Converter Cable with FTDI Chip Support 5V 3.3V 2.5V 1.8V TTL - 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-U09G USB to TTL Serial Cable Built-in FTDI FT232RL IC 1.8M/5.9FT --- ## 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://grenada.desertcart.com/products/157344980-model-sh-u09c5](https://grenada.desertcart.com/products/157344980-model-sh-u09c5) --- *Product available on Desertcart Grenada* *Store origin: GD* *Last updated: 2026-10-04*
