This voice record/playback device is based on ISD1820 chip, which can record/playback multiple-message. It can offer true single-chip voice recording, non-volatile storage, and playback capability for 8 to 20 seconds. For the sampling rate of 3.2KHz it can record for the total duration of 20 seconds.

Feature:

  • Push-button interface, playback can be edge or level activated
  • Automatic power-down mode
  • On-chip 8Ω speaker driver
  • Can be controlled both manually or by the microcontroller
  • Sample rate and duration changeable by replacing a single resistor
  • Record up to 20 seconds of audio
  • On board record/play button
  • On board microphone
  • Repeat/One Time mode select
  • External connector for speaker
  • The chip has the major pin leads, through which you can control the operation from the microcontroller
  • High-quality, natural voice restored, used as a loudspeaker module
  • 3-5V operating voltage
  • Dimensions: 37 x 54 mm

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 (4-12kHz 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.
