Re: No audio output on Respeaker 2mic hat from the JST2.0 Out

Hi there,

there is no switch, plug the speaker to jst2.0 and aplay the wav files. you can hear the voice from speaker.

what kinds of speaker do you use?

you also can plug another usb cable to 2 mic pi hat mic micro-usb port to provide the sufficient power supply for speaker. thanks.

Hi there,

the module interface is UART. So it can work with Raspberry Pi 2. You can use the python language, for the library, you can refer to wiki c++ library. thanks.
