TPA3110D2 2.1 Channel Bluetooth 4.1 Digital Amplifier Board 2 x 15W + 30W with Volume Controls
Make your own 2.1 channel small multimedia wireless Bluetooth amplifier or portable speaker with this 2 x 15W + 30W amplifier board. The board accepts 8 VDC to 20 VDC which makes it perfect for making home or mobile audio projects. Make your audio project truly portable by adding three to five 18650 Li-Ion batteries.
These boards are pre-tested and pre-assembled, which makes your project easy to complete. The on-board jacks, potentiometer, and screw terminals let you get this board powered up and playing music in minutes. Just connect your power source to the DC input screw terminals and run speaker wire from the six screw terminals to you speakers and you're done. For the most wattage output use 19 VDC power adapter. Use the 3-pin connector with 20" (508 mm) cable for internal line-in audio. Unpair your Bluetooth device and the board switches to line-in. No hiss or popping noise when searching for Bluetooth or powering on and off.
