Footprint figures:

• less than 400Kb for an OPC UA toolkit Nano server
• 220 Kb for a Publisher/Subscriber

As SDKs cannot be certified directly, OPC UA certification process has been made using the sample server application that comes with the S2OPC SDK and has been created using the SDK (toolkit_demo_server)
