1 General Description

This document describes the S-VM1010-C Evaluation Kit PCB. The Eval PCB provides the
necessary circuitry to carry out evaluation of the VM1010 ZeroPower Listening
microphone. The board consists of the VM1010 ZPL bottom port MEMS microphone, a
configurable threshold resistor circuit, current sense chip 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, mode and output pins of the mic and the current sense
pin of the circuit.

2 Pinout and Pin Descriptions

The board is shown in Figure 1 as follows and the corresponding pins in table 1 have
been labeled:
