The Bricklet features 2x 8 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. The input/output voltages can be switched manually between 3.3V and 5V*. Via terminal blocks all signals and GND can be accessed. An additional terminal block delivers the switched output voltage.
Human interfaces, such as switches, push-buttons and LEDs are typical applications of this Bricklet.

* The maximum output voltage depends on the supply voltage. If the connected Brick is powered over USB, 5V may not be reached. The reason for this is a voltage drop about 0.5V caused by protection diodes on our products. If you need to reach 5V, you have to use a stack supply, e.g. the Step-Down Power Supply.
