Directions for use:
1. Connect speakers:The speaker two thread ends at of is connected to the amplifier board audio output port, left sound channel the positive line connect power amplifier board LOUT port, the cathode connect to GND.Right track the positive line power amplifier board the ROUT of port, the cathode connect to GND.
2. Connect audio source:Use a 2 core audio line, connected to the amplifier board of 3 p audio input, connect the other side of the audio line plug to (such as computers, mobile phones, MP3, DVD, etc.)
3. Connect the power supply:Use 1.8-12 v dc output of the power adapter/battery/charging etc all can treasure.Will two dc power cord is connected to the amplifier board.2 p power source port, the positive line to VCC, negative to GND, the connection is important to make clear is negative, not blindly wiring, if meet the could seize power amplifier board.
4. :Put through power supply, amplifier board into working state;You can the befond of according to oneself to adjust the volume knob, you can enjoy the magical of eagle amplifier board.

This board features:
adopts TDA2822M power amplifier chip, it has many advantages such as small static current, crossover distortion characteristics.Suitable for portable, miniature tape recorder, computer audio power amplifier.In the era of portable tape recorders, almost 85% are TDA2822M amplifier chip.
Amplifier with the volume control potentiometer, convenient for the user to adjust the volume size, at the same time Presented a cap quality knob.
The audio all adopt the wiring seat, users do not need to use soldering iron, as long as a small screwdriver can easy wiring.
circuit boards have a Screwdriver screw terminal and do not need to use the soldering iron can fast connection, even if you don't have any basis for , see the wiring diagram is also very easily, DIY power amplifier so simple.
