Voice Recorder DIY Kit (20s) with Mic and Speaker

Description

Voice Recorder DIY Kit based on the ISD1820 integrated circuit, which can record a sound or voice message through microphone, and play it back using a speaker. The audio is stored in nonvolatile memory.

The Voice Recorder DIY Kit is a perfect beginner project to leave a lovely little note for someone, like a birthday wish or a shopping list.

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. The 2 slide switches are used to activate the “pass through” function, which means the board only operates as microphone amplifier, or for the “loop” function, which plays the recorded sound continuously.

Functions:

• Automatic power-down mode
• On-chip speaker amplifier
• 2.7-4.5V power supply
• Manual or remote control (GPIO)
• Recording of up to 20s of audio
• microphone and speaker included
