Low power Bluetooth™ Module with antenna- F2M03GLA
Datasheet
6.6 PIOs
The F2M03GLA have 10 programmable general-purpose I/O ports PIO[11:2] and two analog I/O ports
AIO[1:0]. PIO lines can be configured through software to have either weak or strong pull-ups or pull-
downs.
All PIO lines are configured as inputs with weak pull-downs at reset.
AIO[1:0] functions available via these pins include an 8-bit ADC but can also be used as general-purpose
I/O lines. Typically the AIO[0] is used for battery voltage measurement. The voltage range for AIO[1:0] is
constrained by the internal analogue supply voltage which is 1.8V.
Note:
The PIO and AIO lines are controlled by firmware specific settings. Please see specific firmware datasheet for
information about the PIOs used!
