TPA3116D2 Stereo Class-D Amplifier Board

Build a two-channel speaker amplifier around a compact Class D module. This TPA3116D2 board provides left and right audio amplification for DIY speaker and audio projects, letting you develop the enclosure, controls and power arrangement around a ready-made amplifier stage.

✅ Power left and right speaker channels - The two-channel board provides separate amplification for a stereo audio build.

✅ Start with an assembled amplifier module - The ready-made stage lets you focus on wiring and project integration.

✅ Use a range of speaker impedances - Listed 4, 8 and 16-ohm compatibility offers several speaker-matching options.

Make the Amplifier the Starting Point of Your Build

A DIY audio project brings several parts together: the source, amplifier, speakers and supply. This board handles the amplification stage, giving you a defined component around which to plan the rest of the assembly.

Output power depends on supply voltage, speaker load and operating conditions. Use the two-by-50-watt figure as the listed rating, then design the power supply and cooling for the actual load instead of assuming the same output in every setup.
