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. From these, you can easy control record , playback and repeat and so on.
Push-button interface, playback can be edge or level activated
Automatic power-down mode
On-chip 8 Ohm 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.
