Voice Recorder Module 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 ISD1820 Voice Recorder Module is a perfect beginner project to leave a lovely little note for someone, like a birthday wish or a shopping list.
Control the ISD1820 Voice Recorder module's functions through push-buttons or a connected microcontroller. A "pass through" function, when the board only operates as microphone amplifier, or a "loop" function, which plays the recorded sound continuously, can be activated using jumpers.
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
