Overview
CANTest is an open-source printed circuit board by ElBabar, from the ElBabar/CANTest repository on GitHub. It is a 2-layer board of 97 × 58 mm with 33 parts on 94 nets, routed with 589 tracks and 0 vias.
It is built around the MCP2551-I/P and MCP2515-I. Its parts include 10 resistors, 8 diodes, 7 ICs, 4 capacitors and 2 crystals.

PCB/README.mdCANTest
A board designed to test CAN connectivity between 2 arduino nanos
The CAN bus is made using mcp2551 and mcp2515.
LEDs were placed to monitor SPI and CAN activity for debug purposes. A new, cleaner version is being designed (see TXDemo).
This designed was intended simple on a single faced PCB in order to produce it with tools I had under hand.

Questions
How big is the CANTest PCB?
It measures 97 × 58 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CANTest use?
33 parts, built around the MCP2551-I/P and MCP2515-I. 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 CANTest KiCad files?
From the ElBabar/CANTest repository on GitHub, at the commit this page was made from: the board is PCB/CANtest.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CANTest design in my own project?
Its repository states no licence, so its author keeps all rights: ask ElBabar before reusing the design.
