Note:
- Before initiated the module, both pin4 and pin6 should be powered.
- After the module initiated, you can cut off the pin4 3.3V (when there are no users use it)
- When there is a finger touch the sensor, the pin5 will output high level signal
- After your MCU detected high level signal, then your MCU can power pin4 3.3V on
- After the module into capture or identification mode, the pin6 still need to be powered
- When there is no finger on the sensor for a long time (time out), your MCU can turn pin4 off.
