PCB project to aid CAN wire distribution
This PCB can be ordered from any fab house using the files in the gerbers directory of this repository, including oshpark.
Apply a piece of electrical or kaptop tape to the bottom of the PCB if it is going to be mounted diretly to a conductive surface.
Parts:
The PCB uses push to connect terminal blocks. The part footprint is designed to allow any style connector that's typically found in this spacing.
We tend to use the Combicon PTSA family of pheonix contacts ordering yellow and green pairs and then manually assemble them in alternating colors. Works with stripped wire (no connector/ferrule required) 16-24 awg.
These connectors are also typically stocked at mouser. They can also be had from ebay/aliexpress. We haven't had problems with the off-brand ones, but YMMV.

Questions
How big is the CANJunction PCB?
It measures 34 × 22.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CANJunction use?
8 parts. 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 CANJunction KiCad files?
From the jcorcoran/CANJunction repository on GitHub, at the commit this page was made from: the board is CANJunction.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CANJunction design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
