Description
DC 3.5V-16V KA2284 Power Audio Voltage Level Indicator Battery Capacity Indicator Red Green LED for Voltmeter Volume VU Meter
The KA2284 Adjustable Voltage Level Indicator Module provides a logarithmic visual indication of a static or dynamic voltage level using LEDs. Features: Uses KA2284 5-Dot LED Level Meter Driver w/ built-in rectifying amplifierAdjustable voltage range with LED displayUse with AC or DC voltages3.5 to 16V operationThe module can be used to indicate a voltage level such as for monitoring a DC battery level or for use with AC signals to implement a VU meter for audio strength or similar applications. The module uses the KA2284 LED Dot Level Meter Driver IC to implement a logarithmic LED dot indicator display. The display consists of 5 LEDs – 3 green, 1 yellow and 1 red which are lit in sequence as the input voltage increases. A single-turn potentiometer is used to set the range for the display. The input for the voltage measurement includes a series capacitor for use with AC waveforms. There is a small jumper on the board which shorts this capacitor so that the module can be used with a DC signal such as when monitoring battery. Jumper OFF = Monitor AC voltageJumper ON = Monitor DC voltageThe module can be powered off a wide voltage range of 3.5 to 16V Module ConnectionsThere is a 4-pin header on the assembly for making connections. 1 x 4 Header VCC = Connect to 3.5 to 16VIN = Input. The voltage to be measured by the deviceGND = Ground. There are 2 ground pins, but only one needs to be usedGND = Ground. There are 2 ground pins, but only one needs to be used Package Included: 1 x KA2284 Voltage Level Indicator Module
