OBD To RS232 Interpreter

The ELM327 builds on improved versions of our proven ELM320, ELM322, and ELM323 Interfaces by adding seven CAN protocols to them. The result is an IC that CAN automatically sense and convert the most common protocols in use today. There are a number of other improvements as well a high speed RS232 option, battery voltage monitoring, and customizable features through programmable parameters, to name only a few.
