Module Pin Notes:
Note 1
The internal output of 1.8 V power supply provides maximum 30MA current, and the specific use method
can see the application circuit diagram
Note 2
Provid voltage reference to I/O, such as：PIO, UART, SPI, I2S, PCM,etc
Note 3
Regulator enable input.Can also be sensed as an input.
Regulator enable and multifunction button. A high input (tolerant to VBAT) enables the on-chip regulators,
which can then be latched on internally and the button used as a multifunction input.
* The PIN on electricity than VBAT_IN and VDD_IO foot 100 ms delay.
Note 4
Using USB function and Lithium battery charging function, the pin should connect 5V voltage
Note 5

C Serial Clock and Data.
It is essential to remember that pull-up resistors on both SCL and SDA lines are not provided in the module
and MUST be provided external to the module.
Note 6
For customized module, this pin can be work as I/O Interface.
Note 7
1, When you need to use the USB function,
this pin needs to be connected to 3.3V (voltage range: 3.1V~3.6V)
