Mono Class D Digital Amplifier Board

This TPA3255 single-channel Class D amplifier board is designed for compatible DIY audio systems, subwoofer projects, speaker builds, and equipment repair applications. The mono channel layout supports one amplified output, while the full-range/subwoofer switch allows the board to be configured for different audio playback setups. It operates on a DC 32V–48V power supply and supports 2–8 ohm speaker impedance when matched with appropriate components. The onboard heat sink and side aluminum rails help support heat dissipation during operation. This amplifier board is suitable for audio hobby projects, powered speaker systems, subwoofer enclosures, and custom sound equipment installations.
