Grove - Recorder V3
This is the latest version of Grove-recorder, and also the best version. Comparing the
previous one, there are some updates that we would like to mention.
First change is MCU. In V3.0, the MCU is upgraded from to be 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 have ever used previous version, you would know that if you want to
play back what you have recorded, you need to press another button on the Grove
button that connected separately. In V3.0, we integrated the record button and play
back button in to one button. By holding the button for 2 sec, it starts recording, by push
the button quickly, it plays back what has been recorded. What's new in V3
