Two-channel stereo amplifier module Key specifications - Input Voltage: 5V DC (max 5.5V) - Power Output: 3 W per channel (3 W + 3 W) - Speaker Load: 4 to 8 ohms per channel - Channels: 2 (Stereo) Why this matters - Low voltage operation: Power from common 5V supplies, making it easy to use with USB adapters or small wall adapters. - Sufficient powered output: 3 W per channel provides usable volume for compact speaker setups without requiring high voltage. - Flexible speaker compatibility: Supports standard 4–8 ohm speakers, giving you choices for pairing. - Stereo performance: Two channels enable distinct left and right audio for a fuller listening experience. Practical applications - Desktop or multimedia setup: Upgrade a compact computer or media player with a dedicated two-channel amplifier powered from a 5V supply for better sound. - DIY speaker projects: Integrate into small, self-contained speaker systems or embedded audio projects that use 4–8 ohm drivers. - Educational or display setups: Power a simple stereo sound system for classrooms, kiosks, or demonstrations where reliable low-voltage audio is desired. Notes - Ensure the power supply remains within the 5V DC range and does not exceed 5.5V to maintain safe operation. - Use speakers with an impedance of 4 to 8 ohms per channel for proper performance.
