ReSpeaker 6-Mic Circular Array Kit Schematics

Hello all!



I was wondering if it would be possible to receive the schematics for the ReSpeaker 6-Mic Circular Array baseboard and microphone board?



Best regards.

Hi there, we will release the schematic in future and not this moment. thanks for understanding.

Hi Bill,



Thank you for your response. Do you have a indication when how soon in the future the schematics will be released?



Best regards.

I am also interested in the schematics, please do share.

Hi there,



I do double confirm with project managers and the decision is not to open the schematic. thanks for understanding.



Bill

I understand on not sharing the schematics, but can you at least share the pinout for the ribbon cable and the mating connector PN?



I want to use this board for a project, but I need to have a different audio input from the microphones you provide. I can reuse the base board if I can get the pinout for the ribbon cable.

Hi there,



Sure, here are the system diagram, connector info. thanks.

Thanks! Glad you can help to share these details.



Can you fill in the pi header pinout details so I can be sure to not conflict with the pins being used by this board?

Hi there,



Please refer to below. thanks.

Hi, Could you please post the details of the loopback from the speaker/ headphone connector to ADC2 that is seen in “https://files.seeedstudio.com/wiki/ReSpeaker_4-Mics_Linear_Array_Kit/img/voice_hat_acc.png”?

Does the 3.5 audio connector has a mic input or is it only output?
Thanks.

Hi Bill,

The links to system diagram and connector info are not valid. Can you post them one more time?

Hi,

You mean you have managed to duplicate the 6 mic array HAT? Does it work with the Kit?
I want to make flexible PCB based on the 6 mic array hat. Can you share the design info like components and wiring details.

Thx

Hi Bill,

I just want the design of the 6Mic array HAT because I want to make flexible PCB with 6 mic. Can you share? Anyway there is not much tech info, right? Just some components and wiring details. I even don’t need the LED.

@djsg This should be opened up. @jiachenglu Please open the design file for the microphone section.

Hi @djsg
Here is the mic specification.
