General Description
This document describes the S-VM3000-C Coupon PCB evaluation board. The coupon PCB
provides a quick and simple way of evaluating the Pulse Density Modulation (PDM) digital
output microphone, VM3000. The board consists of a VM3000 bottom port MEMS
microphone and a 0.1uF power supply bypass capacitor along with an edge connector.
The user can simply use a corresponding female connector (CW Industries CWR-170-10-
0000) or solder wires to make good electrical contact to the power and output pins of the
microphone.
