Questions tagged [elm327]

The ELM327 abstracts the low-level protocol and presents a simple interface that can be called via a UART, typically by a hand-held diagnostic tool or a computer program connected by USB, RS-232, Bluetooth or Wi-Fi. New applications include smartphones.

The ELM327 is a programmed microcontroller produced by ELM Electronics for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 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.

ELM327 is one of a family of OBD translators from ELM Electronics. Other variants implement only a subset of the OBD protocols.
