Description:
The Voice Recorder and Playback Module featuring the ISD1820 chip is a versatile solution for high-quality audio recording and playback applications. This module allows users to record up to 20 seconds of audio, which is stored in non-volatile memory, ensuring data retention even without power. Equipped with an onboard microphone and an 8Ω 0.5W speaker, it facilitates immediate recording and playback without the need for additional components. Its compact design and ease of use make it ideal for various projects, including voice reminders, interactive toys, and educational tools.
The module operates on a 2.4V to 5.5V DC voltage range, making it compatible with a wide array of microcontroller platforms. It offers both standalone operation via onboard push buttons and microcontroller control through exposed pins, providing flexibility in integration. The sampling rate and recording duration can be adjusted by modifying a single resistor, allowing customization based on specific application requirements. With its automatic power-down feature, the module conserves energy by entering standby mode after each playback cycle.
