• 100% New and High Quality 3 + 3 Watt Digital Stereo Amplifier Board Module
• Using High Quality PAM8403 Digital Amplifier IC with Volume Control and On / Off
• Low Current Consumption, DC 2.5V – 5.5V, can be powered by USB port
• Only for Small Speakers, 4-8 ohm up-to 3 Watts per Channel
• Note: The installation and usage of these modules require some basic knowledge of electronics, if you don’t know how to install, please don’t buy it.

Model: PA8403

Power: Low Power

Excellent noise suppression, in the absence of circumstances connected to input audio ear close to the speaker can not hear any noise, two-channel stereo, 5V power supply can output 3W 3W power, can directly drive 4Ω, 8Ω small speakers, the output power large, full of energy, good sound quality. The unique non-LC filter Class-D digital power board can be directly used computer USB power supply. Double panel wiring, wiring properly resolve the ground potential caused by balance and inter-channel cross talk, ultra-miniature design, can easily be placed in a variety of digital products within a small space, high amplification efficiency. All using the whole plate welding machine, welding quality comparable non-manual soldering iron!

100% brand new and high quality

Operating voltage: 2.5V-5.5V

Maximum output: 3Wx2 (5V 4 ohms)

Efficiency can reach above 90%, you can use the computer USB port 5V power supply

The board compact with a switch potentiometer, you can adjust the volume and control of arbitrary power switch.

Working voltage should not exceed 5.5V, the power of positive and negative can not be wrong. Otherwise, there is the possibility of damage chip

Board size: 2.9cm x 2cm /1.14 x 0.78 inch (Dimensions without potentiometer handle protruding parts)

Note:

Please make sure the power supply is not more than 5.5V and

Please don’t do reverse polarity for “+” and “-“, or else, it will burn the board.

Size for manual measurement, there may be a 0 to 1 cm error, belongs to the normal phenomenon.
