additional module, such as LIN, Bluetooth or wireless network.


The software architecture for the BuildRS platformis also modular: “The software and hardware have a constantly growing portfolio of possible functions, which correspond to the functionality of the peripheral board,” explains Tomic. The systemcan be configured or reprogrammed via the CAN interface.
