If you want change the record duration, an external resistor is necessary to select the record duration and sampling frequency, which can range from 8 – 20 seconds (4-12 kHz sampling frequency). This voice record module provides default connect to a 100k resistor through P2 by short cap. So the default record duration is 10s.
