ProductDescription :

This sound/voice recorder module is based on the ISD1820 integrated circuit, which can record multiple sounds or voice messages through the on-board microphone. The audio is stored in nonvolatile memory.

The sample rate and recording length can be set up by changing a resistor. The resistor R4 on board has 100kOhm, setting the recording length to 10s with a sample rate of 6.4kHz. By replacing this resistor, sample rates from 3.2 to 8kHz can be selected, resulting in a recording time of 8 to 20 seconds (see the datasheet for details).

The on-board push buttons can control the ISD1820 module’s function, or through its control pins, connected to a microcontroller like Arduino, STM32 or PIC, for example.

Functions:

• Automatic power-down mode
• On-chip 8 speaker driver
• 2.7-4.5V power supply
• Manual or remote control (GPIO)
• Adjustable sample rate
• Recording of max. 20 seconds of audio
• Dimensions: 39 x 42 mm
• on-board microphone included
• external speaker included
