* Required Fields



With the WIFI Extension 2.0 you can control Bricks and Bricklets wirelessly over your mobile phone, tablet or PC. For an explanation of the Master Extension concept please take a look at the general description.

Since the device itself handles TCP/IP packages generated by the API, it is possible to connect directly from your controlling device (mobile phone, tablet, (embedded) PC). A Brick Daemon is not necessary.

To use the WIFI Extension 2.0 a Master Brick is mandatory. The RED Brick is currently not supported. If you want to use other Bricks, you can build a stack and plug them also on top of the Master Brick. If you want to use Bricklets you can attach them to the Master Brick or to other Bricks in the stack. From the programming perspective this is completely transparent, i.e. all Bricks and Bricklets can be used exactly the same way as if they were connected to your controlling device via USB.

You need a Master Brick with firmware version 2.4.0 or newer to use this extension.

The following combinations with other Extensions in a stack are possible (regardless of order):

  • WIFI 2.0 / RS485 Master
