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
I
2
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)
2, when the No. 39 PIN (VCC_CHG) with a 5V input pin,
this pin outputs 3.2V ~ 3.4V (maximum current: 250mA)
Note 8
Analog input voltage range: 0~ 1.3V
Note 9
By default, this PIN is an empty feet. This PIN can connect to an external antenna to improve the Bluetooth
signal coverage.
If you need to use an external antenna, by modifying the module on the 0R resistance to block out the
on-board antenna; Or contact Feasycom for modification.
