Description
The ELM329L is a low voltage version of our popular ELM329 integrated circuit. It supports all of the features of our current ELM329 IC, and only differs physically in how pin 6 is used.
The data sheet discusses the ELM329L in detail, how to use it and how to configure it, as well as providing some background information on the protocols that are supported. There are also schematic diagrams and tips to help you to interface to microprocessors, construct a basic scan tool, and to use the low power mode. Because of the similarity with the ELM329, much of this data sheet has been copied from the ELM329 data sheet.
Throughout the document, we use the term ‘ELM329’ to refer to either the ELM329 or the ELM329L. If there is something different between the two, we are specific as to which it applies to.
