This stereo audio amplifier kit can be used with any personal stereo equipment, including MP3 players.

It can be powered by a 9V battery connected to the PP3 clip or you can use a power supply in which case you would need to buy a 2.1mm PCB Mount DC Socket and solder that to wires which you would then in turn solder to the PCB in place of the PP3 jack.

It uses a TDA2822M audio amplifier IC which can output 1W per channel. The kit is supplied with two speakers and a pre-made 3.5mm jack plug.

Features:

1W per channel stereo amplifier.
