Overview
CANdiBar is an open-source printed circuit board by CRTified, from the CRTified/CANdiBar repository on GitHub, published under the MIT licence. It is a 4-layer board of 88 × 44 mm with 67 parts on 75 nets, routed with 570 tracks and 78 vias.
Its parts include 20 ICs, 16 capacitors, 16 resistors and 7 connectors.

IMPORTANT
This project is very experimental. While it works for me in my Voron V0.2, do not assume that it works for you. Proceed at your own risk.

What is this?
This repository aims to contain a small CAN bus and power distribution board. However, I wanted to avoid making all devices connected by a stub.
Properties:
- Seven ports for a 2x3P Molex MicroFit 3.0
- USB2CAN adapter compatible with candlelight
- Proper CAN setup (No star topology that makes everythin a stub)
- Pass-through connection configurable by jumper
- Termination on last slot (might require pass-through on multiple ports)
Why?
I wanted to try atopile and a simple distribution board seemed like a great fit to test the whole design process.
I also wanted to have a sane piece of hardware for simplifying the wiring in my 3D printer, as the Voron v0.2r1 gets pretty crowded when using more than two MCUs.

Questions
How big is the CANdiBar PCB?
It measures 88 × 44 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CANdiBar use?
67 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 CANdiBar KiCad files?
From the CRTified/CANdiBar repository on GitHub, at the commit this page was made from: the board is elec/layout/default/candi-bar.kicad_pcb and its schematic elec/layout/default/candi-bar.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CANdiBar design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
