ReSpeaker USB Mic Array

An out-of-the-box voice pick-up device is the voice of the customer. 

During the past year, Respeaker Mic Array V2.0  has been sold out for more than 10K units in the format of the development board. Customers keep requesting a complete device with an enclosure, which is challenging for them to design it, considering the acoustic principles.   

And here Seeed provides the answer with ReSpeaker USB Mic Array:

• An out-of-box device with a well-designed acoustic structure brings the flexibility for the customer to build in their solution. 
• Mold injected enclosure available, saves the time to go to the market and the mold cost.

The difference between the PCBA inside ReSpeaker USB Mic Array and Respeaker Mic Array V2.0:   

• Optimized power circuit
• Move the audio jack and micro USB port to the backside.
