The KA2284 Power Level Indicator Module is a compact and versatile voltage monitoring board designed for real-time visual indication of voltage levels. Utilizing the KA2284 LED dot level meter IC, it converts analog voltage signals into a 5-segment LED display with a logarithmic scale for precise measurement. This module can monitor both AC and DC voltages, selectable via an onboard jumper, making it highly adaptable for various applications such as battery level displays, audio VU meters, and power supply monitoring. A built-in rectifying amplifier ensures accurate response to input signals, while the adjustable potentiometer allows calibration to the desired voltage range. With its bright LED indicators and simple 3-pin interface (VCC, IN, GND), the KA2284 module offers an efficient and user-friendly solution for embedded electronics, robotics, and industrial circuits.
