ISD1820 Voice Board Module Recording with Terminal

The ISD1820 Voice Board Module records a short voice message and plays it back at the press of a button. Built around the ISD1820 single-chip record and playback IC, it has a microphone, record and play buttons and a speaker output on the board, and the message stays stored even with the power off. It works on its own or triggered from an Arduino.
