USB Control Module 1-Channel 5V Relay Module (No Driver Needed)

USB control relay module for PC and single-board computer switching, this 1-channel 5V relay module lets you turn a connected circuit or device on and off through USB without needing extra drivers. Designed as a simple USB relay interface, it is useful for home automation, test benches, kiosks, robotics, power cycling, alarm control, and other projects that need reliable computer-controlled switching. The 5V relay format fits common electronics workflows, and the no-driver-needed design makes setup faster on systems like Raspberry Pi, Linux boxes, and Windows PCs for scriptable relay control from software, utilities, or custom apps.
