The TZTEK GEACX2 controller is a domain controller specially designed for mobile robots, robotaxi, robobus and other autonomous vehicles. There are two NVIDIA Jetson Orin computing units inside, which have the computing capabilities of multi-sensor fusion perception, planning, prediction, decision-making and so on. The mainboard is embedded in Infineon Automotive Grade multi-core MCU TC397, which can perform key tasks such as vehicle control and system state management. The built-in GPS module and CPLD chip provide UTC time information and UTC time aligned trigger signals to different processors and sensors of the controller, so as to keep the time synchronization of the whole sensing, computing and control system. GEACX2 supports GMSL camera, laser radar, millimeter-wave radar, ultrasonic radar and other commonly used sensors.
