Overview
CAN Distributor is an open-source printed circuit board by ETAChalmers, from the ETAChalmers/CAN-Distributor repository on GitHub. It is a 2-layer board of 140 × 60 mm with 32 parts on 14 nets, routed with 375 tracks and 26 vias.
It is built around the CL25N8-G. Its parts include 16 connectors, 3 diodes, 1 resistor, 1 IC and 1 fuse. It belongs with the interfaces and adapters boards of this library.

RJ10 Pinout (4P4C)
Equivalent with RJ22. Pinout is based on the CANOpen standard, as specified in:

RJ45 Pinout (8P8C)
Pinout is based on the CANOpen standard, as specified in:

Board Concept
Each distribution card delivers CAN and optionally power to its Nodes. Power is only distributed over the Node ports. This is to avoid any complex problems regarding PSU load sharing, ground loops, etc... Power is indicated by PWR_LED. Voltage and allowable current draw depends on the connected PSU.
It is not reasonable to draw more than 200/300 mA over the RJ10 cables.
The board has a footprint for a termination resistor, which may be populated. The resistor should only be populated if the board is at one of the two edges of the CAN network.
The Main ports and Node ports use different connectors to avoid plugging them wrong. The RJ10 ports may either be populated with TE Connectivity's vertical 5520257-2 connectors or horizontal 1-1705949-1 connectors.
Mechanical
All mounting holes are for M3.
The board can be mounted to a DIN rail using Phoenix Contact's 1201578 or 1200993 rail adapters. In that case the board is screwed to the adapters using self tapping M3 plastic screws.

Questions
How big is the CAN Distributor PCB?
It measures 140 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CAN Distributor use?
32 parts, built around the CL25N8-G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the CAN Distributor KiCad files?
From the ETAChalmers/CAN-Distributor repository on GitHub, at the commit this page was made from: the board is CAN-Distributor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CAN Distributor design in my own project?
Its repository states no licence, so its author keeps all rights: ask ETAChalmers before reusing the design.
