This voice Record Module is base on ISD1820, capable of multiple‐message record/playback.It can offers true single‐chip voice recording, no‐volatile storage, and playback capability of about 10 seconds. You can control this module via direct control by push button on board or use an Arduino control record , playback and looping.
Features
- Push‐button interface, playback can be edge or level activated
- Auto power‐down mode
- On‐chip 8Ω speaker driver
- Power Supply – 3V – 5V
- Can be controlled both manually or by a microcontroller
- Record up to 10 seconds of audio
- Size: 38 x 42 mm
Pin Configuration
- VCC – 3 – 5 V power supply
- GND – Power ground
- REC – The REC input is an active‐HIGH record signal. The module starts recording whenever REC is HIGH. This pin must remain HIGH for the duration of the recording. REC takes precedence over either playback (PLAYL or PLAYE) signal.
- PLAYE – Playback, Edge‐activated: When a HIGH‐going transition is detected on continues until an End‐of‐Message (EOM) marker is encountered or the end of the memory space is reached.
- PLAYL – Playback, Level‐activated, when this input pin level transits for LOW to HIGH, a playback cycle is initiated.
- Speaker Outputs – The SP+ and SP‐ pins provide direct drive for loudspeakers with impedances as low as 8Ω.
- MIC – Microphone Input, the microphone input transfers its signals to the on‐chip preamplifier.
- FT – Feed Through: By connecting the mini jumper, this mode enable the Microphone to drive the speaker directly.
- P‐E – By connecting the mini jumper, Play the records endlessly.
