If you are using an Arduino Mega, D2 is not available anymore. More details please refer to Arduino Software Serial( https://www.arduino.cc/en/Tutorial/Softwar...

Re: Noise Suppression/Multiple DOA

Hi there

For the first question, it does not support to detect 2 DOAs at one time.

For the second question, respeaker core v2.0 has 2 call back channels, one is from 3.5mm audio jack and other is from speaker port. so it supports cancel the background music. thanks.

Re: maximum power consumtion

Hi there,
