FLICKER Click is the perfect, simple solution if you need to turn a device on and off at specific time intervals, like blinking LED commercials, alarm system lights, or any other signalling lights.

Thanks to the onboard NE556DR dual precision timer from Texas Instruments and the G6D-ASI power PCB relay from Omron, the FLICKER Click can control loads up to 5A, 250 VAC/30 VDC at a predefined time interval.

The on/off period can last from 0.1 to 6 seconds, that can be set by the two ON/OFF onboard potentiometers. The external load can be connected to the board through the screw terminal. FLICKER Click runs on 5V power supply and it communicates with the MCU over RST pin.
