Description
This module is a mono (1-channel) audio amplifier based on the LM386 chip. To make stereo amplifier, you need two of this module on each channel. It operates at 4V ? 12V and provide up to 325mW of power. The output can drive loads from 4 to 32 ohms. The lower the resistance of the load, the more power it can provide, so a 4 ohm speaker will be about twice as loud as an 8 ohm speaker. The gain is fixed at 200x, but volume can be adjusted using the potentiometer on the module.
Features

- Maximum voltage : 15 V
- Power output : 325 mW (at 6V) or 500 mW (at 9V)
- Gain is 200x of the original signal, adjustable via potentiometer
