For maximum connectivity, netPI/Edge Gateway “Connect” devices have a slot at their bottom for the insertion of various extension modules named NPIX (NetPIeXpansion). A containerized Node-RED software example under https://hub.docker.com/r/hilschernetpi/netpi-nodered enables their immediate use when installed. The source code is open, linked, and serves as a programming reference for other programming scenarios/languages. The NPIX board/slot dimensions and connector assignment are publicly accessible to the public and allow developers to create their own NPIX-designs.
