Frequently asked questions
How do I connect it to a phone?
Power the board, then pair your phone, tablet or laptop with it over Bluetooth as you would with any Bluetooth speaker. Once paired, the audio plays through the board's output.
Can I connect speakers directly to it?
Check the supply voltage, speaker impedance and output power in the manufacturer's datasheet before wiring speakers, since the listing does not specify these values. Use speakers rated for the amplifier's output.
