Recording Times
It is important to use the right SD card capacity according to our planned recording session. The formula to calculate
the space required is:
Time = SD card capacity / (sampling rate x 2)
For example a 32GB SD card can contain about 11 hours if the sampling rate is 384kHz = 41666 seconds = ~11 hours.

Customization
For specific application where the plastic components and aluminum tube are not required and a specific
sensor is needed, the bare circuit can be used.
Due to the high versatility and the very low noise circuitry, the board can be used in a variety of custom
applications.
