The DFRobot 386AMP audio amplifier module is based on the LM386 low-voltage audio power amplifier IC. With a fixed voltage gain of 26 dB (20× amplification) and static power consumption of only 24 mW at 6V, it's well suited for battery-powered applications.
Connect a microphone, MP3 module, or other audio source to the input, and the amplifier drives the included speaker. It's a straightforward way to add audio output to Arduino projects, robots, or interactive installations.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
