ISD 1820PY 3V to 5V Voice Recording & Playback Module with Onboard Microphone and 0.5W 8 Ω Resistance speaker. In the ISD1820 module, flash memory is embedded in the board used to save voice recordings. As this is a non-volatile memory, it can keep data stored even without power input. There is an internal audio amplifier in the module, which is used to drive a speaker of up to 8 ohms 0.5W load. Playback can be edge or level activated via a push-button interface. ISD1820 Voice Recording module can be used for multi-segment recording. The mic is present on board, and there are two pins (SP+ and SP-) present onboard to connect the speaker. 

ISD1820 module, i.e., Vcc, GND, FT, REC, PE and PL. Vcc and GND are used to power up the module by 3V-5V DC. FT pin is used to activate Feedthrough mode. In Feedthrough mode, the input voice through the mic is played directly through the speaker. Whenever the REC pin receives an active high signal module starts recording the voice. PE is an Edge-activated pin, and it remains activated until the End of the Message(EOM) or the end of the memory space is reached. PL is a level-activated pin. When the level changes from low to high, it starts a playback cycle.

There are three buttons on the ISD1820 voice recording module, which are REC, PLAYE and PLAYL. The REC button, as the name suggests, is used to initiate the voice recording. The voice is recorded for the time the REC button is kept on hold. When the REC button is released, the module stops recording the voice. By pressing PLAYE button whole speech can be played back. The PLAY button works on trigger mode. Whereas the PLAYL button works in jog mode. Hence, the voice recording is played back for the duration of time the PLAYL button is kept on hold. As soon as the PLAYL button is released, playback stops.
