Mono Audio Amplifier Kit V3.0 for Personal Stereo

This simple electronic kit provides a complete solution for constructing your own functional audio amplifier. It is designed for use with a wide variety of personal stereo equipment, such as MP3 players, making it an ideal and educational component for amplifier case design projects, school technology lessons, or DIY electronics enthusiasts.

Supplied as an unassembled kit, it requires basic soldering skills to build, offering a rewarding hands-on experience. The core of the amplifier is the NCP2890 audio amplifier IC chip, capable of delivering a clear 1W of output power to the included 8-ohm, 66mm diameter speaker. This provides ample volume for personal listening or small projects.

Key Features & Specifications

• Power Supply: Versatile and portable, the amplifier runs from any DC voltage source between 2.2V and 5.5V. It includes a battery cage designed to hold 2x AA batteries (batteries not included) for easy mobile use.
• Complete Kit Contents: You receive all necessary electronic components: the amplifier PCB, a battery cage, an 8-ohm speaker, a 3.5mm mono jack lead, two 1uF capacitors, one 100nF capacitor, one 100K resistor, and one 15K resistor.
• Compact Design: The printed circuit board (PCB) itself is compact, with dimensions of 1.6mm (height) x 44.5mm (width) x 35.5mm (depth), allowing it to fit neatly into custom enclosures.

Building this kit is a fantastic way to learn about audio circuitry, component identification, and soldering techniques, resulting in a practical and usable electronic device.
