h1. Go 12V

The 5V line already dropped to 4,7V in good condition. I had big problems with
4
* sensemux
5
* CANDis displays got resetted on bad conditions
6
* Not sure if other issues have been related to poor voltage
7
* maybe need higher voltages in the future for bigger displays

24V would be nice but some CAN transceivers can only toleryte CAN-Hi/Low up to 14V.
10
Hard to find voltage regulators from 12V to 3V.
11
Is there one that can handle both 12V and 5V? -> CANDis
