The Bricklet features 4 I/O pins that can be independently configured as digital inputs or outputs. Each input pin can additionally be configured with a pull-up or as interrupt source. Via terminal blocks all signals can be accessed. Two additional terminal blocks deliver 3.3V and GND.
Human interfaces, such as switches, push-buttons and LEDs are typical applications of this Bricklet.
The IO-4 Bricklet 2.0 has a 7 pole Bricklet connector and is connected to a Brick with a 7p-10p Bricklet cable.
