es.
They can be setup in software as a signal output of 3.3v,
a logic level input reading pin (note there are not internal pull-up resistors),
or a pwm (pulse-width modulation) output signal.
The CORE I/O also provides pins that provide power out at 5V, 12V, and 24V.
There are also 2 pins providing i2c communication SDA (data) and SCL (clock).</p>
