The Keyestudio 4-Channel 5V Relay Module is an electronic switching board designed to control multiple electrical devices using Arduino-compatible boards and other microcontroller systems. It features four independent relay channels, allowing users to switch up to four separate circuits through low-voltage control signals.
Operating with a 5V control supply, this module is suitable for automation projects, smart home applications, lighting control, and DIY electronics. Each relay provides switching contacts that allow connected devices to be controlled independently by a compatible controller. The module helps interface low-voltage microcontroller circuits with external electrical loads, provided the relay ratings and safety requirements are observed.
