TPA3110 XH-A232 30W+30W Stereo Audio Amplifier Board 8-24VDC
The TPA3110 XH-A232 is a compact stereo audio amplifier board designed for DIY audio builds, speaker projects, and amplifier replacements. Based on the TPA3110 amplifier IC, it delivers 30W per channel (30W + 30W stereo) and runs from a wide DC 8–24V power supply.
The board features clearly marked connection pads for easy wiring: left and right audio inputs (Lin, Rin) with ground (GND), power input (+/−), and dedicated speaker outputs with polarity markings (+R− and +L−). A large blue anodized aluminum heatsink covers the amplifier section for efficient heat dissipation, while four 330µF 25V electrolytic capacitors (CE1–CE4) and output filter inductors (L1–L4) help ensure stable, clean operation. Four corner mounting holes (O1–O4) allow secure installation in enclosures. The board measures 53 × 45 mm.
