This board was based off my schematic and code, which is hosted at: https://github.com/lincomatic/LeafCAN

You can get information on how to get Arduino set up to compile my firmware from my blog: http://blog.lincomatic.com/?tag=can-bus
Note that the board has 2 serial ports. The idea is to use the first port to communicate with the board via an FTDI cable for logging and control.
The second port is for hooking up a bluetooth adapter.
There is a row of I/O pins broken out, too for other enhancements.
Since the board supports only 1 CAN transceiver, you can select the active BUS via the jumper block.
I am going to add some code soon to support a pushbutton to toggle the display.
Right now, it stays powered up even when the car is turned off. I am thinking of adding some code to shut off the backlight
after a few minutes of inactivity on the CAN bus.
If anyone makes any useful changes to the firmware, please send them to me, so that I can update the repository on github.
I will get the latest Eagle files from Chris and update that on github, as well.
Let me know if you need any help to get it up and running w/ the firmware compilation.
