This sound detector is based off the ISD1820, which is 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 board is loaded with a sample which is 3.2k with a the total 20secs for the recorder. This module is very easy use offering direct control by the push button on board or by any microcontroller such as Arduino.
This incredibly small stereo amplifier is surprisingly powerful – able to deliver 2 x 3.7W channels into 3 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, its incredibly efficient (over 90% efficient when driving an 8ohm speaker at over a Watt) – making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. This board is a welcome upgrade to basic “LM386” amps!
This panel mount 6.3mm stereo jack is perfect for adding an audio connection with your project! Simply mount this jack to your panel, connect the wires and you will be ready to go!
This 3.5mm stereo plug comes with a metal relief. Simply unscrew the metal relief and connect your wires to it to make an audio connection!
This VS1053 MP3 Shield is an easy way to play audio files from the Arduino. For the best headphone listening experience, the VS1053 includes EarSpeaker spatial processing which accurately simulates how a room with stereo loudspeakers would sound. In addition to being able to decode all major formats, VS1053 is capable of recording in Ogg Vobis files.
