Digital voice recorder 40s

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.
