Description

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.
