= Usage Tips =

The VC01 and VC02 kits use the same development board with different module footprints . For quick testing, the board comes preloaded with a demo firmware with "小安小安" wake word . Customize voice commands using the opensource SDK .

Use the on-board reset button to enter programming mode after connecting USB
Keep the microphone 30-50cm away for best recognition performance
Firmware version must match board model
