ISD1820
Voice Record Module is base on ISD1820, which a multiple-message record/playback device. It can
offers true single-chip voice recording, no-volatile storage, and playback capability for 8 to 20 seconds.
The sample is 3.2k and the total 20s for the Recorder.
This module use is very easy which you could direct control by push button on board or by Microcontroller
such as Arduino, STM32, ChipKit etc. Frome these, you can easy control record , playback and repeat and
so on.
Feature
Push-button interface, playback can be edge or level activated
Automatic power-dwon mode
On-chip 8Ω speaker driver
Signal 3V Power Supply
Can be controlled both manually or by MCU
Sample rate and duration changable by replacing a single resistor
Record up to 20 seconds of audio
Dimensions: 37 x 54 mm
If you want change 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). The Voice
Record Module of our provide default connect 100k resistor through P2 by short cap. So the default record
duration is 10s.
