Embedded computers undertake a wide range of roles within the field of aviation. They keep them in the air with various sensors and instruments, and within the commercial sector they also provide inflight entertainment and information to the passengers on board. The entire range of Toradex modules is extremely lightweight and features a very compact form-factor. System-critical data is stored in non-volatile flash memory, ensuring that a system failure is virtually impossible. The high computing performance combined with a huge variety of input and output capabilities make our modules ideal for literally any purpose inside and around airplanes: Flight computers and instrumentation, collision detection, automatic emergency landing systems, video transmission, radar, cabin control and infotainment are some of the examples where our modules are integrated. Even unmanned drones are controlled by our computer on modules.
