Description
This is an electronic voice memory that can record and play back audio to and from a non-volatile memory. By selecting different sampling frequencies, up to 240 seconds of audio can be stored in memory. Default sampling frequency is set to 8kHz, which provides a recording length of 40 seconds. The module can record from either line-level or mic-level inputs. It can be controlled externally from a microcontroller via SPI or directly via onboard pushbuttons.
* Supply voltage: 8 – 24VDC
* Sampling frequency: 4kHz – 12kHz
* Recording time: 26 – 80s (40s default)
* Control: SPI, stand-alone (push buttons)
* Audio input: built-in microphone, line-in
* Audio output: Speaker, line-out
* LED indicates recording / playbac
