This user guide applies to the following MEMS microphone evaluation boards:
This is a simple board that allows quick evaluation of the performance of the ICS‐43434 MEMS microphone. The small size and low profile of the flexible PCB enables direct placement of the microphone into a prototype or an existing design for an in situ evaluation. The board consists of an I²S‐output microphone soldered to a flexible PCB. The only other component on the board is a 0.1 μF supply bypass capacitor.
The flex PCB design mates to a 6‐position ZIF connector with 0.5 mm pin spacing, such as the Molex 0527450697 connector. The flex PCB mates to the connector by first pulling out the connector’s clamp, inserting the flex PCB, and then pushing the clamp closed. Wires can be soldered directly to this connector’s pins or it can be mounted directly on a rigid PCB for evaluation. We recommend to use 28 AWG or smaller wire for soldering to this connector’s pins. The PCB thickness at the pin edge is 0.3 mm.
