MONKMAKES Amplified Speaker V2 Board 20g

The MONKMAKES Amplified Speaker V2 Board is a compact, powerful mono speaker module on a PCB, designed specifically for adding high-quality sound to single-board computer (SBC) and microcontroller projects. This versatile board simplifies audio integration, making it an ideal component for makers, educators, and electronics enthusiasts working with platforms like Raspberry Pi and Arduino.

Its core function is to accept an audio signal via a standard 3.5mm stereo jack input. The board then internally mixes the stereo signal to mono for clear output through the integrated speaker. For more advanced audio applications, such as those using Pulse-Width Modulation (PWM), the board provides convenient header pins for both a direct line-in connection and a low-pass filtered input. This flexibility allows for clean sound reproduction from digital audio sources.

The speaker itself is robust, with a maximum power output of 500mW and an 8Ω impedance, delivering ample volume for prototypes, alerts, or simple multimedia projects. Powering the module is straightforward, as it operates on a wide voltage range of 3.3V to 6V, which can be conveniently supplied directly from the GPIO pins of a Raspberry Pi or the power rail of an Arduino board.

With its minimal footprint and pre-soldered components, the Amplified Speaker V2 is a true plug-and-play solution that eliminates the complexity of building an audio amplifier circuit from scratch. It's perfect for creating talking devices, interactive exhibits, sound-enabled gadgets, or educational tools where reliable audio feedback is required.
