Overview
CanankaFEC is an open-source printed circuit board by medo64, from the medo64/CanankaFEC repository on GitHub, published under the MIT licence. It is a 2-layer board of 24 × 27.9 mm with 28 parts on 31 nets, routed with 326 tracks and 31 vias.
It is built around the PIC18F25K80-I/MM, MCP2561-E/P and FT232RL, with the BSS84 and B3B-XH-A among its other parts. Its parts include 8 capacitors, 7 resistors, 3 ICs, 3 transistors and 2 connectors. It belongs with the interfaces and adapters boards and the PIC boards of this library.

README
README.mdCAN Bus Framework Expansion Card
Cananka allows for the computer control of a CAN bus. The control of device is possible via serial port (SLCAN compatible, Windows/Linux) or via SocketCAN network driver (Linux).
CAN Bus Pinout
To connect to this board, one has to use a 4-pin JST XH connector. The following table represents the pinout, pin 1 being on the left as looking into the expansion card.
| # | Ref | Description |
|---|---|---|
| 1 | GND | Ground connection |
| 2 | CAN L | CAN low-side |
| 3 | CAN H | CAN high-side |
| 4 | V+ | Not connected |
As power consumption is low, wires can be almost any AWG. I would recommend using 24 AWG wire 0.25 mm² as they allow for greater compatibility with other connectors.
LEDs
Left LED will blink on UART communication with computer (both sending toward and receiving data from computer).
Right LED will blink on CAN bus activity.
Other repositories
The following hardware version are also available:
- Full (isolated and in the case)
- Framework Expansion Card (non-isolated, in framework expansion card format)
- HAT (intended for Raspberry Pi)

Questions
How big is the CanankaFEC PCB?
It measures 24 × 27.9 mm and has 2 copper layers, 0.8 mm thick.
What parts does the CanankaFEC use?
28 parts, built around the PIC18F25K80-I/MM, MCP2561-E/P, FT232RL and BSS84. 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 CanankaFEC KiCad files?
From the medo64/CanankaFEC repository on GitHub, at the commit this page was made from: the board is src/CanankaFEC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CanankaFEC 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).
