- Easy-to-use with sound volume control, record, playback functions and Grove interfaces.
- Easy to be programmed for plenty of applications with MCU.
- Automatic power-down mode, variable recording and playback duration, non-volatile storage.
- Low power consumption.
- Shipped with a speaker (8Ω/2W).
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.

Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfil a variety of needs. Not only are these open hardware, but we also have open-source software.
