Almost all of the automobiles produced today are required, by law, to provide an interface for the connection of diagnostic test equipment. The data transfer on these interfaces follow several standards, but none of them are directly usable by PCs or smart devices. The ELM327 is designed to act as a bridge between these On-Board Diagnostics (OBD) ports and a standard RS232 serial interface.
The Device is a programmed microcontroller produced by ELM Electronics for translating the on-board diagnostics (OBD) interface found in most modern cars. The Device command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors.
The original ELM327 is implemented on the PIC18F2480 microcontroller from Microchip Technology.
