KA2284 Battery and Power Level Indicator provide a logarithmic visual indication of a static or dynamic voltage 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 5 LEDs – 3 green, 1 yellow and 1 red which is lit in sequence as the input voltage increases. A single-turn potentiometer is used to set the range for the display.
