1 Channel 5V Relay Module Arduino Compatible BK008
A single-channel 5 V relay module that allows a microcontroller to switch high-voltage electrical devices up to 250 VAC or 110 VDC. Controlled via a standard TTL-level digital IO pin, it works with Arduino and other popular microcontrollers.
The module uses an SRD relay with optocoupler isolation (EL817) and includes a status LED to indicate whether the relay is energised. Its compact form factor is designed for dense PCB mounting.
