It is a mono Class D audio amplifier board capable of delivering 100W @ 2 Ohm. It employs TI' TPA3116 Amplifier IC to achieve high efficiency and good performance. The module dissipates only 1.1W with no signal when in ON mode (around 0.07W when in stand-by mode). The optimized heatsink design provides enough cooling for most applications and eliminates your worry over heat dissipation. Over current protection, over temperature protection and reverse polarity protection are included to extend the longevity of the amplifier board and ensure its reliability.
