			== Getting started with CAN bus ==
			A CAN bus needs to be terminated on each end and the iPDM56 gives you the flexibility to terminate either CAN1 and/or CAN2 with jumpers. We need 4 pins and 2 jumpers (e.g. from a PC mainboard) each and something to hold them in place while soldering - I used a third hand, but tape should work, too.

			Pre-assemble the jumpers and pins to ensure proper fitting, then solder the pins in.

			If you have v1.1 of the iPDM56, as per https://github.com/celeron55/ipdm56/tree/master/ipdmhw1.1, R97 needs to be replaced with a 1k resistor or CAN won't work. The existing SMD one can easily be "wiped off" with the soldering iron. I bent a through-hole version to fit as we're already soldering. Leaving the leads on until last allows you to check if the connection is solid.
