IO-16 Bricklet 2.0

Features

  • 16-channel digital input/output
  • Switchable logic voltage 3.3V or 5V*
  • Configurable pull-ups and interrupts

Description

The IO-16 Bricklet 2.0 can be used to extend the features of Bricks by external digital inputs and outputs.

The Bricklet features 2x 8 I/O channels that can be independently configured as digital inputs or outputs. Each input channel 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 IO-16 Bricklet 2.0 has a 7 pole Bricklet connector and is connected to a Brick with a 7p-10p Bricklet cable.

* The maximum output voltage depends on 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.

** depends on your system (OS, CPU etc.)

Test your IO-16 Bricklet 2.0

To test a IO-16 Bricklet 2.0 you need to have Brick Daemon and Brick Viewer installed. Brick Daemon acts as a proxy between the USB interface of the Bricks and the API bindings. Brick Viewer connects to Brick Daemon. It helps to figure out basic information about the connected Bricks and Bricklets and allows to test them.

Connect the IO-16 Bricklet 2.0 to a Brick with a Bricklet Cable.

If you connect the Brick to the PC over USB, you should see a new tab named "IO-16 Bricklet 2.0" in the Brick Viewer after a moment. Select this tab.

If everything went as expected the Brick Viewer should look as depicted below. You can change the values of the channels, use them as input or output, enable/disable pull-ups and try out monoflops.

After this test you can go on with writing your own application. See the Programming Interface section for the API of the IO-16 Bricklet 2.0 and examples in different programming languages.

Case

A laser-cut case for the IO-16 Bricklet 2.0 is available.

Case for IO-16 Bricklet 2.0

The assembly is easiest if you follow the following steps:

  • Screw spacers to the Bricklet,
  • screw bottom plate to bottom spacers,
  • build up side plates,
  • plug side plates into bottom plate and
  • screw top plate to top spacers.

Below you can see an exploded assembly drawing of the IO-16 Bricklet 2.0 case:
