Grove - Recorder v2.0 is an upgraded recorder with enriched features. It can record 8-20 seconds of audio with high-quality and natural voice. In addition, it also gets sound volume control and playback functions. With MCU such as Seeeduino or Arduino board, you can prototype various applications quickly with user-friendly interfaces. Recording time could be customized(if you require) by replacing the different resistor and the solution to do this will be described in later sections.
Features
Specification
Parameter | Value |
---|---|
Operating voltage | 3.3~5.0V(DC) |
Ripple(at Max power) | = 50mV |
Recording duration(default) | 12 seconds(MAX value) |
Playback duration(default) | 12 seconds(MAX value) |

Chip | ISD1820PY(Datasheet), NS8002(Volume Amplifier) |
Note
The playback duration will be the same with Recording duration as it changes. Different kinds of resistors will lead to different Recording durations as the following table shows.
ROSC | Duration | Sampling Frequency | Input Bandwidth |

80 KO | 8 secs | 8.0 kHz | 3.4 kHz |
100 KO (default) | 10 secs | 6.4 kHz | 2.6 kHz |
120 KO | 12 secs | 5.3 kHz | 2.3 kHz |
160 KO | 16 secs | 4.0 kHz | 1.7 kHz |
200 KO | 20 secs | 3.2 kHz | 1.3 kHz |
