The MIC Click Board™ carries the SPQ0410HR5H-B surface mount silicon microphone with maximum RF protection. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over the AN pin on the mikroBUS™ line.
How Does The MIC Click Board™ Work?
The MIC Click Board™ contains a silicon microphone, which outputs the signal to the analog pin (AN) on the mikroBUS™ line via the op amp.
SPQ0410HR5H-B FEATURES
The SPQ0410HR5H-B is a miniature, high-performance, low power, top port silicon microphone.
Using the SiSonic™ MEMS technology, the SPQ0410HR5H-B consists of an acoustic sensor, a low noise input buffer, and an output amplifier.
MaxRF protection prevents RF noise in traces from getting into the mic output.

OMNIDIRECTIONAL MICROPHONES
SPQ0410HR5H-B is an omnidirectional microphone. As the name implies an omnidirectional microphone can hear equally in all directions. So whichever way you hold it, up or down, it will work the same.
