However the unit only comes with a very basic control software which is basically a 9600 dumb terminal into which you have to enter +AT commands to control the relay. I wrote my own front end which for me worked great. I now have an ON/OFF button that I can press. Review: Works okay - It works well once you find some software which can drive it easily. Refuses to work with my terminal software but found a web based script which works a treat. Using it to reset a remote reset an arduino. ## Features - USB Relay Controller:With this USB Relay controller, you can control the switch on your PC or laptop. - Silicon Labs CP2102N Serial Chip:You need to install the driver the first time you use it, and a virtual serial port will appear on your computer.

However the unit only comes with a very basic control software which is basically a 9600 dumb terminal into which you have to enter +AT commands to control the relay. I wrote my own front end which for me worked great. I now have an ON/OFF button that I can press. ### ⭐⭐⭐⭐ Works okay *by B***U on 8 November 2024* It works well once you find some software which can drive it easily. Refuses to work with my terminal software but found a web based script which works a treat. Using it to reset a remote reset an arduino. ### ⭐⭐⭐⭐⭐ Review *by S***Y on 13 July 2025* Bought this to replace a different USB relay that quit working after a month. PLUSES: +Plastic housing. No worries about shorting out the bottom of the PC board. So often you get a circuit board with NO mounting holes or other way to support it. +Wonder of wonders, IT SHIPS WITH A USER GUIDE! ON PAPER! What a concept! Minor gripes: -The housing on this is a little bigger than it needs to be. -The user guide makes no mention of the timing constraint for inputting control strings. Likely a lot of the reviews saying it doesn't work were a result of that. If I hadn't seen the reviews taking about the timing, I'd would have probably returned this. -It's a little weird for this to very loosely be emulating the old smart modem AT command set, but then trading away carriage return to terminate commands and using timing instead. The gripes are pretty minor vs the pluses. I hope this one lasts. ## Frequently Bought Together - DSD TECH SH-UR01A USB Relay Controller for Computer and Laptop(1CH) - Electromagnetic Power Relay, 8-Pin 10 AMP 24V DC Relay Coil with Socket Base, LED Indicator, DPDT 2NO 2NC - MY5NJ 2PCS [Applicable for DIN Rail System] - JESSINIE USB Serial Port Control Relay Module Sturdy Durable Lightweight USB Relay Module USB Intelligent Control Switch Overcurrent Protection Intelligent Command Control Switch Intelligent Home --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/412333021-sh-ur01a-usb-relay-controller-for-computer-and-laptop-1ch](https://www.desertcart.kg/products/412333021-sh-ur01a-usb-relay-controller-for-computer-and-laptop-1ch) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-20*
