DS2413 1-Wire Two GPIO Controller Breakout

GND
Ground connection for the DS2413 1-Wire GPIO breakout. Adafruit Learn wiring says GND connects to Arduino GND.
Type · ground
IO
1-Wire bus signal. Adafruit Learn wiring says IO connects to an Arduino GPIO pin and uses a 4.7 kΩ pull-up resistor.
Type · signalVoltage · Pull up IO to the controller supply, 3.3V to 5V per the Adafruit product page wiring note.
PIOA
One of the two DS2413 controllable I/O lines. Adafruit states PIOA and PIOB can be used as inputs or outputs and are open-drain.
Type · gpioVoltage · Open-drain output, use a remote/pull-up supply appropriate for the controlled circuit.
PIOB
Second DS2413 controllable I/O line. Adafruit states PIOA and PIOB can be used as inputs or outputs and are open-drain.
Type · gpioVoltage · Open-drain output, use a remote/pull-up supply appropriate for the controlled circuit.
