OPA2134 – Dual Channel Audio Amp

The Sound Recorder Module uses the ISD1760 Chip to record and store voice signals. ISD1700 series recording chip is a kind of high integration, high performance chip. This module can do multiple recording, the sampling rate can be set to 6k or 8k by the on-board resistor. There are also some inside sounds to remind the user working state of the module, such as record beginning, record stopping, record erasing , etc. The recording data is stored in the FLASH, without any compression to ensure the quality of the recordings. You can easily control this module manually or with an Arduino by SPI interface.

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.
