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).
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.
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.
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)
