Stereo amp board for 12–28 V systems

The Vszerda XH-M314 uses a TPA3118 chip to deliver two channels of 45 W each. It accepts a DC supply between 12 V and 28 V and includes Bluetooth input for wireless streaming. The compact board suits car audio upgrades, smart-home speaker projects or small home-theatre subwoofer builds where a simple stereo amplifier is needed.

Thermal behaviour under continuous playback

The TPA3118 runs in class-D topology, so efficiency stays high during long listening sessions. Heat rises gradually rather than spiking, allowing the board to maintain rated output without thermal shutdown in typical enclosed installations. Builders who need sustained high-power output for large passive radiators or multi-driver cabinets should verify heatsink capacity for their specific enclosure.
