### Features

- Communicate directly with Bricks/Bricklets without Brickd

- Supports 10/100 Mbit/s Ethernet (1000 Mbit/s compatible)

- Integrated PoE Power Supply (PD Class 0 for IEEE 802.3af)

- Can power a Stack via Ethernet Cable

### Description

With this Ethernet Extension you can control [Bricks](http://www.tinkerforge.com/en/doc/Primer.html#primer-bricks) and [Bricklets](http://www.tinkerforge.com/en/doc/Primer.html#primer-bricklets) and integrate them into a [LAN](https://de.wikipedia.org/wiki/Local_Area_Network). 10BaseT/100BaseTX Ethernet is supported and the module is 1000BaseTX compatible. The Extension is available in two variants: The PoE variant features a integrated [PoE](https://en.wikipedia.org/wiki/Power_over_Ethernet) power supply. It allows to power the connected modules over industry standard IEEE 802.3af, such that a PoE injector as well as PoE switches can be used to power [stacks](http://www.tinkerforge.com/en/doc/Primer.html#primer-stack). Additionally a variant without PoE is available.

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](http://www.tinkerforge.com/en/doc/Software/Brickd.html#brickd) is not necessary.

To use the Ethernet Extension a [Master Brick](http://www.tinkerforge.com/en/doc/Hardware/Bricks/Master_Brick.html) or [RED Brick](http://www.tinkerforge.com/en/doc/Hardware/Bricks/RED_Brick.html) is mandatory. If you want to use other Bricks, you can build a stack and plug them also on top of the Master Brick or RED Brick. If you want to use Bricklets you can attach them to the 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.
