Input power voltage tolerance

Hey guys,
what is the voltage tolerance for power input? I’ve noticed that the supplied power source gives 12V and I’m wondering if if would be possible to power the device from standard car battery which gives voltage 10-14V, or I need to use a regulator to get constant 12v voltage


Unofficial answer out of the schematic:
You should be within 10% of 12V. The input protection circuit will get upset at 13.3V to 14.7V.
Lower voltages seem fine to me as long as these are not too far from 12V and you don’t need the internal 12V connector.
