It’s Here – the ELM327L v2.2

We have updated the ELM327L integrated circuit to v2.2, matching the features of the recently updated ELM327. Here’s what we changed:

  • AT CS command now shows CAN frequency
  • Added 12500 and 15625 bps baud rate options for ISO 9141 and ISO 14230
  • New AT CER hh command allows defining the CEA Rx address
  • New IFR modes 4,5,6 control J1850 IFR sending while monitoring
  • Added PP 1F to allow KWP length to include the checksum byte
  • Default value of PP19 increased from 31 to 4F

There are no physical changes with the new ELM327L v2.2 – it remains pin compatible with the previous version. For more information, and to purchase the IC, go to the ELM327L web page.

Application Note 02 has been updated

We’ve just updated the ‘ELM327 Circuit Construction’ Application note, to reflect the small changes we’ve made to Figure 9 over the past few years. While we’ve continually updated the ELM327 data sheet, we failed to keep the App Note current. Recent comments by one of our customers brought this to our attention.

All of our Application notes are available in the Help section, under Application Notes.

Christmas Shutdown

It’s that time of year again. We take a break from filling orders and answering emails, and spend some time with our families. We do hope that you are able to spend some time with yours.

If you wish to place an order, the system will gladly accept your money. We will not be back to begin filling the orders until January 9, however. As always, we will send you an email when your order does ship.

Best Wishes for 2017 !

A new ELM327 is coming!

A number of people have asked for some small additions to the ELM327 that we agree will enhance the circuit. We’ve been busy adding those changes.

Work is progressing well, and we hope to complete testing soon. When that’s done, and the data sheet has been updated, we will let you know.
