This is the latest version of Grove-recorder. Compared to the previous one, there are some updates that are mentioned below.
First change is the MCU. In V3.0, the MCU is upgraded to the ISD9160FI, which is more powerful than the ISD1820PY. Together with the newly added 2Mbytes flash, it allows you to record up to 83 seconds, much longer than previous 12 seconds.
Second, if you have used the previous version, there where seperate buttons for recording and playback. In V3.0, the record and playback button are integrated into one button. By holding the button for 2 seconds, it starts recording, by push/tapping the button quickly, it plays back what's recorded.
Here is some tips to let you use It better:
When you are using an external signal to drive the grove connector, please toggle the record switch to the Rec side
When you are recording or playing back, don’t push the button until the recording or playing end.
If you are using a third party speaker, pay attention to the input voltage in case of over loading and damaging of the board
