The fischertechnik TXT 4.0 Controller

Program like the pros!

The fischertechnik TXT 4.0 controller comes with many great features! 

The TXT 4.0 controller offers plenty of new features with its 512 MB RAM and 4 GB eMMC memory, the three servo outputs and a capacitive touch display that supports swipe gestures. The improved WLAN and Bluetooth module offers the right wireless interface for numerous applications. 
Another interface is the USB host port, to which, for example, the fischertechnik USB camera or USB sticks can be connected. Up to 8 additional controllers can be connected to one controller as extensions. The flat housing allows the controller to be perfectly integrated into the models. To always be up to date, firmware updates are automatically downloaded via the cloud, preserving custom programs. With the software ROBO Pro Coding can be programmed both graphically and with Python! ROBO Pro Coding is operating system independent and can also be used with mobile devices (Android / iOS). With an additional app (Android / iOS), the TXT 4.0 controller can also be controlled via voice recognition.

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