Hi! I am planning to use a KC868-A8 in a vehicle, power by battery. What is the input voltage tolerance of the board? Could it handle like, 10-15 volts, or do I have to add a regulator to make sure it gets exactly 12V?

it use by DC12v, because the power is directly use by Relay's coin. if voltage is higher, it's not good for relay while work long time.
