ReSpeaker 6-Mic Circular Array Kit Schematics

[info975885]

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 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.

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.

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, 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?

[djsg]

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

[djsg]

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.

[Baozhu]

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

[jiachenglu]

Hi @djsg
Here is the mic specification.

[djsg]

Thank you, guys. Greatly appreciate it. @Baozhu @jiachenglu

[djsg]

Hi @Baozhu,

I am interested in the design of the HAT and we want to buy its design spec and firmware with source code. Can you give me a contact?

[Baozhu]

@djsg I’m really sorry, there is some x-power commercial information in this, we signed an NDA agreement, this is not open source for everyone.
