Power Pins

VIN - This is the power pin. To power the board, give it 2.0V-5.5VDC.
GND - This is common ground for power.

Input Pins

A+ and A- - Audio inputs for the amplifier. Signal goes through 1.0uF capacitors, so they are fully 'differential'. If you don't have differential outputs, simply tie the A- to ground.

Shutdown Pin

SD - The shutdown pin. Can be used to power down the amplifier by tying to ground.

Output Pins

+ and - - Amplifier output pins. They are spaced to allow for a terminal block to be soldered in place. The output is "Bridge Tied" so that the output connects directly to the speaker pins, no connection to ground.
