KA2284 / LB1403 Audio Level Indicator Pro Audio level indicator Module Board, Just connect D.C. Power supply through battery snapper and a audio signal from any audio source volume control. The KA2284 / LB1403 Audio level Indicator Module provides a lvisual indication of dynamic Audio level using LEDs.The module uses the KA2284 / LB1403 LED Dot Level Meter Driver IC to implement a logarithmic LED dot indicator display. The display consists of 11 LEDs – 1 Blue, 6 green and 4 red which are lit in sequence as the input voltage increases. First LED – Blue is power LED indicates power on of the Circuit. A single-turn potentiometer is used to set the range for the display. Module Connections There is a 4-pin header on the assembly for making connections. 1 x 4 Header VCC = Connect to 5 to 9 V – You can Supply voltage through 9 Volt battery snapper also. GND = Ground. ( Power Supply ) – You can Supply voltage through 9 Volt battery snapper also. GND = Ground. ( 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 / LB1403 Supply voltage: 5V-9V PCB board size: 90mm X 44mm X 10mm Packing weight: 100 gm
