LIN to serial port voltage problem [Copy link]

Can an expert tell me, when transferring LIN to serial port, does the voltage at the LIN end have to be 12V? Thank you

uncertain.

The standard voltage of the LIN bus is 12V, but the design and operation do not strictly require 12V.

The LIN-to-serial voltage does not have to be 12V, but using 12V ensures compatibility with most LIN transceivers.

The LIN bus needs a power supply to pull it up. This power supply is usually a 12V battery, so it is definitely necessary

Does LIN need to be converted to a serial port? Isn't it enough to just connect a resistor in series and a voltage regulator directly to the TTL pin?
