This compact stereo LED spectrum level indicator features dual 12-level channels, with 7 green, 2 orange, and 3 red LEDs for vivid music visualization. Each LED has an independent current-limiting resistor to ensure consistent brightness across different colors. The module supports adjustable rise/fall speeds, peak hold, and multiple display modes.
Equipped with automatic gain control (AGC), it adapts to various input levels and ensures accurate, dynamic audio visualization. The audio input is isolated with a TI op-amp to minimize MCU-induced interference.
