Description:
The ISD1820 Voice Board Module is a compact and versatile solution for recording and playing back audio messages. It utilizes the ISD1820 IC and offers non-volatile storage, allowing recorded messages to be retained even after power is removed. The module supports recording durations ranging from 8 to 20 seconds, which are adjustable via an onboard resistor. Thus, it is suitable for various applications such as voice prompts, alarms, and interactive projects.
Equipped with an onboard microphone, the ISD1820 module enables direct recording without external components. It features push-button controls for recording and playback and pin headers for integration with microcontrollers like Arduino or Raspberry Pi. The module includes a built-in 8Ω speaker driver capable of driving speakers directly and offers both edge-triggered and level-triggered playback modes for flexible operation.
