Overview
Simplified can module is an open-source printed circuit board by polymetric, from the polymetric/spicanfd repository on GitHub, published under the Apache-2.0 licence. It is a 2-layer board of 28.4 × 20.3 mm with 18 parts on 21 nets, routed with 88 tracks and 8 vias.
It is built around the MCP2517FD-H/SL and MCP2542FD. Its parts include 5 resistors, 4 capacitors, 2 ICs, 2 connectors and 1 crystal.
Main components
2README
README.mdspicanfd
Add a CAN-FD interface to a microcontroller through SPI. Uses the MCP2517FD chip + ATA6561 transceiver.
Based on Longan Labs' CAN FD Shield for the Arduino Uno. It's basically a breakout board form of that. Their shield is nicer to use but this board is a lot cheaper to fab since it's smaller and has less components.
For usage, please refer to the MCP2517FD datasheet and the acan2517FD Arduino library.

Questions
How big is the Simplified can module PCB?
It measures 28.4 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Simplified can module use?
18 parts, built around the MCP2517FD-H/SL and MCP2542FD. 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 Simplified can module KiCad files?
From the polymetric/spicanfd repository on GitHub, at the commit this page was made from: the board is simplified can module.kicad_pcb and its schematic simplified can module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Simplified can module design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
