Functional descriptions
Power: The module is powered by a DC power source from 2.0V to 3.3V. The absolute maximum voltage that
should be applied is 3.6V. VCC and VSUPPLY are connected through a zero ohm resistor on the module.
The power plane is attached directly to VCC. P3 can carry 100mA per pin; P5 can carry 500mA per pin.
Ground: These are attached to the ground plane of the module. P3 can carry 100mA per pin; P5 can carry
500mA per pin.
General I/O: These are bidirectional, CMOS level, digital signals running between VCC and GND.
General I/O / external interrupt: These are bidirectional, CMOS level, digital signals running between VCC
and GND. They can also be configured as external, hardware interrupts.
General I/O / external interrupt / counter in: This is a bidirectional, CMOS level, digital signal running
between VCC and GND. It can be configured as external, hardware interrupt or as an input to a counter.
Analog In: These are analog inputs.
