IO-4 Bricklet 2.0

Description / IO-4 Bricklet 2.0

The IO-4 Bricklet 2.0 can be used to extend the features of Bricks by external digital inputs and outputs.

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.

This Bricklet ist not galvanically isolated to the Tinkerforge system. This means that there is a direct electrical connection between the terminals of the Bricklet and the rest of the system. Dependent of the application this can lead to undesired connections, ground loops or short circuits. These problems can be prevented by using the Bricklet together with a Isolator Bricklet.
