ISD1820 voice recording and playback module 1. Introduction This module board is based on ISD18B20, which is a single-chip single-message record/playback device. Recordings are stored into on-chip non-volatile memory, providing zero-power message storage. With the embedded Flash memory employed, data retention up to 100 years and typical 100,000 erase/record cycles can be reached. Time for recording is 8-20 seconds Features: 1. Power input: DC 2.4-5.5V 2. With internal audio amplifier, this board can drive 8 Ohm 0.5W speaker directly. 3. Microphone is on board 4. Board dimension: 54mm x 38mm 5.
