Important Technical Note:

Attention! The TPA3110D2 chip on this board supports a maximum of 15W per channel. Running the TPA3110D2 at 30W per channel in stereo mode, even with a heat sink, is not feasible because the chip's design and power handling capabilities inherently limit the maximum power output per channel to 15W into 8Ω (or 10W into 8Ω at lower supply voltages).

Please be aware that many vendors, websites, and content creators claim 30W per channel, which is clearly misinformation and not possible due to the chip's design limitations. The TPA3110D2 datasheet specifies that the maximum output power is 15W per channel for a stereo configuration at 4 ohms with a 24V power supply. Attempting to achieve 30W per channel would significantly overdrive the chip and cause damage.

Always refer to the datasheet when in doubt.

Applications:

Perfect for DIY audio projects, portable speakers, home audio systems, car audio upgrades, and any application requiring efficient, high-quality stereo amplification with minimal power consumption.
