8.5  Digital Microphone 

A low power Knowles SPH0641LM4H digital microphone is incorporated on the board, 
for use with Modules that support direct interfacing to this type of PDM microphone. Note 
that the Knowles digital microphone is designed to be mounted on the underside of a 
board, with audio passing through a hole in the board. 

8.6  USER button  

User Button (SW5) can be used to generate an interrupt by pulling down the P6 pin 41 
(PIO1-1) of the Module to ground. 

A 100KΩ pull-up resistor is also connected to this pin.
