KEYESTUDIO SC8002B Audio Power Amplifier Speaker Module for Arduino Player

The KEYESTUDIO SC8002B Audio Power Amplifier Speaker Module is an all-in-one sound output solution designed for Arduino projects and audio playback. It is ideal for students, educators, and hobbyists looking to add voice alerts, melodies, or sound effects to their microcontroller builds.

All-in-one audio playback design

This compact module integrates an SC8002B audio amplifier chip, an adjustable potentiometer, a built-in speaker, and a standard 3-pin header interface. It provides a complete, plug-and-play solution for sound generation without requiring complex external circuitry.

Signal amplification and music playback

The onboard SC8002B chip amplifies low-power audio signals by approximately 8.5 times, broadcasting them clearly through the speaker. It can function as an external sound amplifier for music playback devices or play custom audio directly from your projects.

Custom sound generation with microcontrollers

By connecting the module to a microcontroller, you can input square waves of varying frequencies and durations to program custom melodies and tones. This makes it an excellent tool for learning coding and interactive electronics.

Electrical specifications and power requirements

Operating at a standard DC 5V with a current draw of 500mA or more, the module delivers a maximum power output of 2W. The integrated speaker produces a sound volume of up to 80dB, suitable for indoor projects and classroom demonstrations.

Safe operation and volume adjustment

To prevent damage or burning out the 0.15W speaker, always adjust the onboard potentiometer to its minimum volume setting before powering on. You can then slowly increase the volume to your desired level once the signal is active.

ROHS compliance and operating limits

This module is ROHS certified, ensuring safe and environmentally friendly construction. It operates reliably within a temperature range of 0 to 40 degrees Celsius, making it robust enough for typical classroom and workshop environments.
