The fischertechnik TXT 4.0 Controller
​

Program like the pros!

The fischertechnik TXT 4.0 controller comes with lots of cool features! With its 512 MB RAM and 4 GB eMMC memory, three servo outputs and a capacitive touch display that supports swipe gestures, it offers lots of new features.
The improved WLAN and Bluetooth module offers the right wireless interface for numerous applications. Another interface is the USB host port, which can be used to connect the fischertechnik USB camera or USB sticks, for example. Up to eight additional controllers can be connected to one controller as extensions. Thanks to the flat housing, the controller can be perfectly integrated into the models. Firmware updates are automatically downloaded via the cloud so that you are always up to date, while your own programs are retained. The ROBO Pro Coding software can be used to program both graphically and with Python! ROBO Pro Coding is operating system-independent and can also be used on mobile devices. With an additional app (Android / iOS), the TXT 4.0 Controller can also be controlled via voice recognition.

But that's not all! Further features and information can be found on the product detail page.
