The RESPEAKER GROVE EXTENSION BOARD is an extension board for the Seeed Studio ReSpeaker series of audio development boards. It increases the capabilities of the original ReSpeaker series with six Grove connectors, allowing additional sensors and components to be connected to an existing ReSpeaker project. These additional sensors/components allow engineers and makers to quickly build more advanced prototypes and projects. The RESPEaker GROVE EXTENSION BOARD also contains a buzzer, two buttons, a potentiometer, a micro USB port for on-board programming, and a variety of power and I/O headers for connecting the board to the ReSpeaker series.
