Frequently asked questions
How do I connect it to speakers?
Connect the board's audio output to an amplifier input or powered speaker, matching the power and ground pins marked on the board. Do not connect bare speakers directly unless the board is designed to drive them.
How do I pair it with a phone?
Power the board, put it in pairing mode, then select the module from the phone's Bluetooth list. Pairing details depend on the board's firmware, so follow any indicator behaviour described in its documentation.
