Hello guys,
I need some information about the microfon from the audio shield VMA02 or KA02. For example i need the frequency respone and the wave-band. Maybe someone has a datasheet of the microfon or someting else. I write an email to the velleman support, but they only send me this link: http://www.velleman.eu/products/view/?id=11733
I would be very grateful if someone could give more informations 
Kind regards Vanessa
