The ELM327L is a new version of the ELM327 integrated circuit that is able to work with supplies from 2.0V to 5.5V (the ELM327 requires 4.2V to 5.5V). It offers all the features of the ELM327, and comes in three different device packages.

We’ve dropped the price of our popular ELM327 integrated circuits. Effective immediately, the single unit prices are:
ELM327 v2.1 – $21.00
ELM327 v1.4b – $21.00
ELM327 v1.3a – $17.00
We are continuing to offer the older v1.3a and v1.4b chips, as promised. See our OBD IC page for data sheets, product comparisons, etc.
The iBook format for our data sheets continues to grow in popularity. The interactive nature and the convenience of being able to easily put all 174 pages of ELM327 information onto your electronic bookshelf is a real plus. Get your free copy through the iTunes store:
Our latest update of the ELM327 integrated circuit is now available! For more information, see our OBD IC page. Just want a data sheet? Then, click here:
The latest version of our ELM327 integrated circuit will be available for sale soon. It takes the ELM327 v2.0 and adds a few more features:
- Now supports ISO15765 and ISO14230 ‘Response Pending’ (7F XX 78) replies
- Has several speed improvements, especially while processing CAN messages
- We’ve added new filters for more precise CAN protocol searches
These changes add to what is already a great chip.
Note that there are no pin changes with this update (so the chip can be used in existing designs), and that the pricing will remain unchanged. Expect to see this new IC in a few weeks time.
As promised, the iBook version of the ELM329 v2.1 data sheet is now ready for download. Many are finding this to be a convenient way to maintain and view reference documents. Visit the iTunes Store to download your free copy:
The latest version of our ELM329 is ready! We’ve made several changes to improve speed and reliability. The biggest visible change is the addition of ‘filters’ that prevent the sending of CAN messages if the baud rate is not correct.
The data sheet has been updated too, with a few new sections. Download a copy using this link:
Our iBook data sheets for the ELM327 and ELM329 integrated circuits seem to be quite popular, so we’ve produced an iBook version for the ELM325 too. If you would like to get your own copy (for the iPad), it’s free, and available through iTunes:
ELM325 J1708 Interpreter
This is another vehicle diagnostics interface chip – this time for heavy duty vehicles that use J1708 with J1587 (or J1922). Although these protocols are being phased out (with J1939 replacing them), there are still a very large number of vehicles that use them.
The ELM325 is very similar to our popular ELM327 – the interface is simple, and can be customized with AT commands, the protocol conversion is all taken care of for you, and the circuit only needs a few support components in order to make a complete interface.
