It is clear that an EIB node or device has to implement (an appropriate subset of) the EIB communication stack presented in the previous section. This is complemented by a multitude of local connectivity and hosting features described below.

A summarised, abstract picture of the architecture of a single node demonstrates how all these elements combine to build an open system concept, which is not bound to any particular hardware, firmware or microprocessor design.

To gain a head start, the interested EIB product developer is encouraged to assess the merits of certified OEM building blocks. A whole spectrum of solutions is available, ranging from fully integrated, general-purpose device nodes, over EIB chip sets, UARTs and transceivers to source code licences.
