I
This pin can be used to put to sleep and wake up the
main microcontroller .
HIGH
= programmable;
LOW
= programmable
15
VCC
I
Power supply input (Input 7). The power supply must be
able to meet the requirements of current consumption.
Care must be taken so that the operating voltage applied
to the terminal stay within the voltage range. Applying a
voltage outside of the voltage range can damage the
module.
