S-VM1000-C

VM1000 Coupon PCB User Guide Rev 1.0 By Shin Nagpal General Description This document describes the S-VM1000-C Coupon PCB evaluation board. The coupon PCB provides a quick and simple way of evaluating the single ended analog output VM1000 microphone. The board consists of a VM1000 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. Pinout and Pin Descriptions The board is shown in Figure 1 as follows and the corresponding pins in table 1 have been labeled: ‘ Figure 1.
