I am preparing to purchase my system. I already have RPi board and need to understand the parts I need to add to this. I have the Carberry board and case. I am wondering about the cables. Since my intention is to use this to display gauges and read diagnostics, which cables would be needed for this?
Also, has anyone used the Carberry system with a battery based mini UPS to keep the system powered between short periods of the car being off? I would like something like this to reduce startup time between stops.
