CKE KA2284 Audio Level Indicator Ready module 10 LED Adjustable DC 5V-9V Display Lights Electronic Hobby Kit

CKE VU CIRCUIT PCB IS BUILT IN KA2284 Audio Level Indicator Pro Audio level indicator Module Board, Just connect Power supply through battery snapper OR Any DC POWER and a Audio signal from any audio source volume control. The KA2284/LB1403 Audio level Indicator Module provides a visual indication of dynamic Audio level using LEDs.The module uses the KA2284 LED Dot Level Meter Driver IC to implement a logarithmic LED dot indicator display. The display consists of 10 LEDs – 2 Blue, 4 green and 4 red which are in sequence as the input voltage increases. Yellow is power LED indicates power on of the Circuit. A single-turn potentiometer 10 K is used to set the range for the display. Module Connections There is a 3 -pin header on the assembly for making connections. 1 Pin Header is of VCC Connect to 5 to 9 V - DC ( Power Supply ) - 2 and 3 Pin Headr for ( Audio Signal ) IN = Audio signal input Feature: The amplitude of the level can be adjusted by variable resistance placed on the circuit board. Specification: Chip: KA2284 Supply voltage: 5V-9V PCB board size: 85 mm X 45 mm X 1.6 mm Packing weight: 20 gm
