Features overview​
The farm-ng Brain is an Alpha level product subject to change. Not all features are fully tested and validated.
The farm-ng Brain brings supercomputer performance to the edge, in a ruggedized packaged designed for the harshest environments. The Brain contains a NVIDIA Xavier NX which has up to 21 TOPS of hardware accelerated computing power for machine learning and AI applications, and paired it with a touch-screen display designed to be outdoor-visible, creating both a user-interface and sensor hub in a single, waterproof package. This provides quick entry into the world of artificial intelligence, and a single packaged solution for developing tools and interfaces for outdoor autonomy.
Includes CAN bus, USB, and GIGe ethernet bus options.
