Overview

Product Overview

A single relay you control from a computer over USB. The CH340 bridge presents a virtual COM port (driver-free on Linux and Raspberry Pi), and a short command at 9600 baud 8N1 switches the SPDT relay — 10 A at 250 V AC or 30 V DC on NO, COM and NC screw terminals. It draws about 70 mA from the USB port, so no external supply is needed. Operate time is about 10 ms, release about 5 ms, with roughly 10 million mechanical cycles.

Script it from Python, Node or a shell script to power-cycle a router, reset a device under test, run a kiosk light or switch a lamp from a Raspberry Pi, Linux box or Windows PC. Rated −25 °C to +75 °C.

Questions & answers

Frequently asked questions

Yes. It is described for Raspberry Pi, Linux boxes, and Windows PCs, using USB for scriptable relay control without extra drivers. It is intended for PC and single-board-computer switching tasks.
Yes. ShillehTek supplies this relay module pre-soldered, and the no-driver-needed USB design reduces setup steps. You still need suitable control software and safe wiring for the circuit or device being switched.
It uses USB as the control interface and provides one 5V relay channel to turn a connected circuit on or off. The provided information does not specify load ratings, so verify suitability before switching higher-power devices.
It fits projects that need computer-controlled on/off switching, such as home automation, test benches, kiosks, robotics, power cycling, and alarm control. It is useful when software needs to trigger a physical circuit.
Check that the USB connection is stable, the operating system recognizes the module, and your utility or custom app is sending the correct command. Also confirm the load is wired to the relay contacts properly.
