Interfacing of ReSpeaker_6-Mic_Circular_Array with Raspberry Pi 3 b+ manually.

Hi,



I have some queries regarding the ReSpeaker_6-Mic_Circular_Array interfacing with Raspberry Pi.



1). Can we connect this module manually(without using of 40 pin header)? If it possible then what are the connections for that?

2). As of now, we don’t want to interface onboard 12 LEDs, because in our application one SPI and one UART port are already used.

3). In our application, we just want speech recognition. Is there any effect on recording without connecting these LEDs?





Thanks in advance!

Hi there,



There is led_en pin, GPIO5. You can set gpio5 as low and disable the leds. thanks.
