Features:
– Can use 5V battery or any USB port to power.
– D class amplifier is highly respected today because its 90% high efficiency. A class, B class amplifier efficiency is only about 30%.
– Temperature does not affect the sound quality so no need to add heat sink therefore less space is taken.
– Module has a short-circuit current protection and over-temperature protection.
– Noise canceling circuit was built in, power on / off without pop noise.
– Can provide 3W (left channel) + 3 W (right channel) output power in the 4Ω load and 5V power supply conditions.
