Thanks to the onboard NA556 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, which 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 Board™ runs on a 5V power supply and it communicates with the MCU over the RST pin.
