  • Can use the computer USB port, USB power bank or a mobile phone charger to supply the 5V support power
  • Battery power can also be used
  • High efficiency: 90%
  • Provides 3W (left channel) + 3W (right channel) output power into a 4Ω speaker load and 5V power supply
  • CMOS class D amplifier design for high efficiency and low cost
  • Noise canceling circuit built into the amplifier board
  • Power on / off without popping noise
  • Integrated power switch and volume control (turn knob fully counter-clockwise to turn off)
  • Module has short-circuit current protection, under-voltage lockout and over-temperature protection (shuts down at an internal temperature of 140C +/- 15C)
