USB‑controlled relay boards provide a simple way to switch higher‑power loads from a computer or microcontroller using the standard USB power and data bus. They are available in a range of channel counts, from a few outputs for basic on/off control to eight‑channel versions that can handle up to 16 A at low voltage or 250 V AC, making them suitable for driving motors, lights, solenoids and other actuators in robotics, automation and prototype systems. Low‑power coil designs keep overall current draw low, while screw terminals give reliable connections for normally‑open, normally‑closed and common contacts. Enclosure options protect the modules and provide convenient mounting, ensuring a tidy, robust integration into any project.
