This is KA2284 Power & Audio Level Indicator Module that can use to check voltage of your battery and audio level of you amplifier. you can adjust level of this meter through potentiometer. before adjust the level of battery or power supply, set potentiometer to 0 level to protect the module by high voltages.

The KA2284 Voltage Level Indicator Module provides a logarithmic visual indication of a static or dynamic voltage level using LEDs.

• Uses KA2284 5-Dot LED Level Meter Driver w/ built-in rectifying amplifier
• Adjustable voltage range with LED display
• Use with AC or DC voltages
• 3.5 to 16V operation

The 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 voltage
• Jumper ON = Monitor DC voltage

The module can be powered off a wide voltage range of 3.5 to 16V

Features:

• Can be controlled by jumper — AC and DC signals can be controlled by jumpers. With LED indicator light, more convenient to use
• Power level indicator module — The power level indicator module is made of high‑quality materials, which has high reliability, sturdy, not easy cracked, can be used for a long time
• Adjustable level — The level can be adjusted and easy to use. Stable performance, safe and reliable to use
• Right audio level indicator module — 100% brand new high quality right audio level indicator module, strictly full tested to ensure the best quality before shipment, safe to use
• Audio Level Indicator Module Specification —- The level can be adjusted and easy to use. PCB Board Size: Approx. 29 * 21mm / 1.1 * 0.8in
