Adjustable Volume: Includes a volume control knob to set the output level for different listening environments, so you get clear sound without distortion in small or large rooms. Performance Amplifier: Uses the LM386 Audio Amplifier Board to deliver up to 10W of mono output, providing sufficient power for compact DIY audio projects with clear, audible sound. Compact and Portable: The mini amplifier module is small and easy to integrate into tight spaces, making it suitable for portable or space constrained builds. Versatile Power Range: Operates efficiently on a DC 312V supply, enabling use with multiple power sources and maintaining reliable performance across varying voltage conditions. Benefits and compatibility Simple integration: Designed to plug into common DIY audio setups, with a single mono output for straightforward speaker connections. Dependable performance: Monophonic amplification that stays effective across a range of voltages, suitable for batterypowered or lowvoltage projects. Space saving: The compact footprint fits inside small enclosures, hobby kits, and compact speakers without crowding other components. Use scenarios DIY portable speaker: Build a small batterypowered speaker by pairing this module with a suitable speaker and power source for portable music or alert sounds. Microcontroller audio alerts: Add audible beeps, chimes, or voice prompts to robotics, educational kits, or DIY projects that require clear mono audio cues. Small project sound system: Integrate into compact enclosures for desk speakers, hobbyist projects, or compact PA style announcements where space is limited.
