This is the latest version of Grove-recorder, and also the best version. Compared to the previous one, there are some updates that we would like to mention.
First change is MCU. In V3.0, the MCU is upgraded to ISD9160FI, which is more powerful than the old one ISD1820PY. How is it more powerful? Together with the newly added 2Mbytes flash, it allows you to record up to 83 seconds, much longer than previous 12 sec record.
Secondly, if you used the previous version, you would know that if you want to play back what you have recorded, you need to press another button on a separately connected Grove button. In V3.0, we integrated the record button and play back button into one button. By holding the button for 2 sec, it starts recording, by push the button quickly, it plays back what has been recorded.
Here is some tips to let you use It better.
