FLICKER Click Board™
Thanks to the onboard NE556DR dual precision timer from Texas Instruments and the G6D-ASI power PCB relay from Omron, the FLICKER Click Board™ 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. The FLICKER Click Board™ runs on 5V power supply and it communicates with the MCU over RST pin.
Note: The FLICKER Click Board™ has exposed pins/pads. To stay safe take precaution when applying high voltage to the click. The click is to be used by trained personnel only when applying high voltage.
Applications
The FLICKER Click Board™ 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 signaling lights.
