The ISD1820 Voice Recording Module is a simple, cost-effective audio record-and-playback solution built around the ISD1820 IC. It records audio using an onboard electret condenser microphone and saves it directly into non-volatile flash memory, keeping your stored voice message safe even when power is turned off.

It offers dual control modes—it can function completely standalone using its onboard tactile push buttons or be triggered via digital pins from microcontrollers like Arduino, STM32, or Raspberry Pi. It also includes an integrated audio amplifier to drive the included 8Ω and 0.5W loudspeaker directly.
