h1. Go 12V
The 5V line already dropped to 4,7V in good condition. I had big problems with
* sensemux
* CANDis displays got resetted on bad conditions
* Not sure if other issues have been related to poor voltage
* 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.
Hard to find voltage regulators from 12V to 3V.
Is there one that can handle both 12V and 5V? -> CANDis
MCP 1754-3302CB: SOT-23-3; MCP1754: max. 17,4V; 300mV dropout; 150mA; 3,3V dropout
MCP1703AT3002ECB: 3,3V
Display braucht schon 120mA: ->250mA
