GPIO Electrical Characteristics
The output is open collector and thus requires a pull-up resistor to operate. The rise time and bias current is determined
by the resistor value chosen. If the camera is generating an output signal that approaches the rise time plus the fall time
of the circuit, care must be taken to optimize the pull-up resistor chosen to minimize the rise time while still remaining
within the current limits of the output circuit.

Warning! To avoid damage, connect the GND pin first before
applying voltage to the GPIO line.
Warning! Prolonged use of the camera outside of the Operating
Range described below may lead to unexpected behavior and should
be avoided.
