CANADUINO® ISD1820 Voice Recording Module - 8 to 20 Seconds Recording Time with Built-in Microphone & Speaker - Perfect for DIY Electronics, Voice Messages, and Educational Projects

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 modeOn-chip 8 speaker driver2.7-4.5V power supplyManual or remote control (GPIO)Adjustable sample rateRecording of max. 20 seconds of audioDimensions: 39 x 42 mmon-board microphone includedexternal speaker includedISD1820 Voice Recording Module Data Sheet
