New Ethernet Master Extension V1.1

by TinkerForge

TinkerFoger made the new Two Ethernet Master Extension Modules with WIZnet W5200 Ethernet control chip. One is with POE. Two is without POE.


With this Ethernet Extension you can control Bricks and Bricklets and integrate them into a LAN. 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 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. Additionally a variant without PoE is available.


  • 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

Ethernet Configuration

The Ethernet Extension can be configured in two different modes: DHCP or static IP. If you use a static IP you have to enter IP, Subnet Mask and Gateway.

The MAC address of the Ethernet Extension is not fixed in hardware, it will be allocated by Tinkerforge. If it is lost in the EEPROM it can be found on the sticker of the Ethernet Extension.

After configuring the Ethernet Extension you have to press the button “Save Ethernet Configuration” and restart the Master Brick
