NBB Controls+Components
Firmware development of a universal receiver for radio control systems from a variety of application areas: The RXC receiver translates control signals from the remote control to the system or vehicle on which the receiver is installed, and presents them in a way the system or vehicle can understand. Furthermore, the RXC receiver can send feedback data from the system back to the remote control display.
