Page 1 of 2 FLICKER click From MikroElektonika Documentation Thanks to the onboard NA556 dual precision timer from Texas Instruments and the G6DASI power PCB relay from Omron, the FLICKER click can control loads up to 5A, 250 VAC/30 VDC at a predefined time interval. FLICKER click The on/off period can last from 0.1 to 6 seconds, that can be set by the two ON/OFF onboard potentiometers (Onboard LED is indicating the duration of relays' ON time). 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.
