Segment Display 4x7 Bricklet 2.0


  • Four 7-segment digits
  • Switchable dots per digit, colon and tick mark
  • Brightness of segments configurable
  • Configurable counter functionality


The Segment Display 4x7 Bricklet 2.0 can be used to control four 7-segment displays, four dots, two colon dots and a tick mark by a Brick. Each of the 35 segments can be controlled independently.

It is also possible to configure the brightness of the segments. Besides the possibility of controlling each segment independently, the API offers a user configurable counter.

Test your Segment Display 4x7 Bricklet 2.0

To test a Segment Display 4x7 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 Segment Display 4x7 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 "Segment Display 4x7 Bricklet 2.0" in the Brick Viewer after a moment. Select this tab. If everything went as expected you can now activate/deactivate the individual segments.

After this test you can go on with writing your own application. See the Programming Interface section for the API of the Segment Display 4x7 Bricklet 2.0 and examples in different programming languages.


A laser-cut case for the Segment Display 4x7 Bricklet 2.0 is available.

Case for Segment Display 4x7 Bricklet 2.0

The assembly is easiest if you follow the following steps:

  • Screw Bricklet to top plate with spacers at the bottom and long screws from the top,
  • build up side plates,
  • plug side plates into top plate and
  • screw bottom plate to bottom spacers.
