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. ## 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? - 🛒 **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.com.br/products/542896278-dsd-tech-sh-ur01a-usb-relay-controller-for-computer-laptop](https://www.desertcart.com.br/products/542896278-dsd-tech-sh-ur01a-usb-relay-controller-for-computer-laptop) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-06-20*
