Grove -Recorder v2.0 (ISD1820PY) with Loudspeaker/Volume Amplifier (NS8002)

Grove - Recorder v2.0 is an upgraded recorder with enriched features and is able to record 8-20 seconds of audio with high-quality and natural voice. Feature Easy to use: Easy to use with sound volume control, recording, playback functions and Grove interfaces Automatic power-down mode: variable recording and playback duration, and non-volatile storage Low power consumption: Enters standby mode immediately following a record or playback cycle Adjustable volume: Shipped with a speaker (8Ω/2W)with high-quality and natural voice Grove compatible interface: The product ensures "Plug and Play" and could be versatile for various applications of Grove 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. What's Grove? We have developed more than 400 Grove modules, covering a wide range of applications that can fulfil various needs. Click to explore the Grove Sensor family and get started to Grove your Idea. For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product. Application Alarms Toys Short-duration-echo required applications 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) Sample rate 53 kHz Chip ISD1820PY(Datasheet), NS8002(Volume Amplifier) Note The playback duration will be the same as the Recording duration as it changes. Different kinds of resistors will lead to different Recording duration as the following table shows.
