WIFI Extension 2.0 available

The new WIFI Extension 2.0 is finally available!

It features the now ubiquitous ESP8266. We use the ESP-WROOM-02 module which is FCC/CE compatible. As you can see on GitHub the development for this new Extension started on July 27th 2015. Nearly one year ago, holy moly!

The new WIFI Extension 2.0 comes with it’s own firmware that can be updated completely automatically by the Brick Viewer through a Master Brick. So you don’t need a FTDI cable or similar to update the Extension. Compared to the old WIFI Extension we have many new features and even more are planned:

Property WIFI Extension WIFI Extension 2.0
Price (incl. VAT) 59.99€ 29.99€
Modes Access point or client Access point or client or both at the same time
Encryption WPA2 for client, WEP for access point WPA2 for client and access point
Tinkerforge Protocols TCP/IP, authentication TCP/IP, authentication, WebSockets
Firmware updates No Yes
Mesh networking No Comming soon
Internal homepage No Comming soon
Weight 18g 12g
External antenna Yes No (PCB antenna only)

Every other property between the two are either equal or very similar (RF output power, etc.). As you can see, the new WIFI Extension 2.0 can replace the old WIFI Extension in all but one feature: You can’t connect an external antenna. We realize that this is necessary for some applications. Unfortunately none of the ESP8266 modules with a external antenna connector that are currently available on the market is FCC and CE compatible. As far as we can tell they have neither been tested, nor would they pass a test.

As a workaround we will still offer the old WIFI Extension for the time being. In the last production run a few weeks ago we made sure to produce a full batch. So we expect the old WIFI Extension to be available as fallback for a long time :-)

Tinkerforge at Automatica 2016

This year the Automatica is from 21st to 24th June in Munich. We will present our building blocks at this trade fair for automation and mechatronics for the first time. We are very curious about the feedback. Our booth is in hall A5 stand 139A. You will be able to see applications four our building blocks in the areas of low cost automation and rapid prototyping.

As an exhibitor we will have an allocation of free tickets again. If you want to visit us at Automatica, please write an email to
