Description
If you're working with DIY projects and need a small speaker output, truly this little gem is a great to have and a serious sounding device to own.
Features:
1.Small footprint(1.85 x 2.11 cm),Loud amplification
2.Two-channel stereo, single 5V power supply, can directly drive any 4-8 ohms speakers
3.High output power, good sound quality
4.Can use the computer USB port 5V power supply or using a mobile phone charger USB port 5V power supply, battery power can also be used
5.High efficiency:85%, can provide 3W (left channel) +3 W (right channel) output power in the 4O load and 5V power supply conditions
6.A class, B class amplifier such efficiency is only about 30%, D class amplifier is highly respected today
7.D class amplifier efficiency is extremely high, not because of temperature affect the sound quality,but do not add heat sink and take less space
8.Noise canceling circuit was built in the amplifier board
9.Power on / off without pop noise
10.Module has a short-circuit current protection and over-temperature protection
