The ELM327L v2.3 is now available!

The newest ELM327L integrated circuit is now available. It provides all of the functions of the current ELM327 but operates over a much wider supply voltage range.

Some of the new features of the new ELM327L are:

  • A new AT FT command that provides more receive filtering
  • Three CAN Flow Control modes for experimenters
  • The Response Pending now works with CAN Extended Addressing
  • New AT IA, and C0/C1 commands
  • Better noise tolerance on RS232 receive

For more information, see the ELM327L web page.

New App Note – RX ERRORs When Monitoring CAN Data

We’ve noticed some changes with scan tool interfaces in some vehicles. While queries for trouble codes, etc. do not seem to be affected, there’s a slight change to how you should monitor data on the bus.

Application Note 08 discusses why you might be seeing RX ERROR messages when monitoring a CAN data bus, and presents one way that we found to fix them. See the Applications Notes page for the download.

Coming Soon – ELM327L v2.3

We’re just doing our final tests on the new ELM327L v.23 integrated circuit. This revision brings all of the full voltage ELM327 v2.3 features to our ELM327L line of products, which allow for operation with as little as a 2.0 volt power supply.

You should be able to purchase it in the next few weeks.

Phasing out ELM327 v2.2

The ELM327 v2.2 integrated circuit has been a strong seller for the past several years, but it was replaced by the ELM327 v2.3 in 2020. We have been selling both products for the past year, but now it is time to stop selling the older v2.2 product.

Over the next few weeks, we will let our v2.2 stocks decline and will eventually no longer sell it. If you have not already migrated to the v2.3 product, now is your time to do so.

Long Lead Times…

It seems that integrated circuit manufacturers are having trouble getting chips out in the time frames that they once did. We’re not really sure why – it could be that Covid has reduced their ability to produce ICs, or possibly that demand has simply exceeded what they have facilities for. No matter what the reason, we are regularly receiving emails from our supplier saying that lead times have been extended.

With some lead times in the 38 week range, we will not be able to fill some of your orders in the short times that you would like. All that we can say is that you should build those times into your planning, and also keep in mind that we will be closed permanently as of June, 2022. Sorry to have to say this.

Thank you for our patience and understanding. Stay safe.

Elm is closing…

… but not until 2022. We’ve had a few questions concerning this, and we have to say that it is true.

We’ve been creating and selling our unique integrated circuits since 1998, and we know that many of our customers have come to rely on our products for their business. For this reason, it is a very difficult decision.

The recent battles with Covid-19 has reminded us of the many great things that life has to offer, however, and for this reason we have decided to close down our business so that we can have more time with family and friends, and maybe pursue some new hobbies too.

We will be closing at the end of June 2022, so you will have almost two years to adjust your production, and consider alternatives.

Many of our customers have become close friends that we have enjoyed working with, and we will certainly miss that. Thank you for the more than 20 years that we’ve had with you. We wish you well in your endeavours, and more importantly, good health.

All of us at Elm

We have reopened as of May 25 !

Life is beginning to return to normal here in Canada, so we now feel that we can safely reopen the business. We still need to take a great many precautions, but that has become the norm and they are becoming routine. It is time to begin serving our customers again, and we are doing so as of Monday, May 25.

Although COVID-19 seems to be under control in many countries, it seems that there are still serious concerns around the world – and this directly affects our ability to fill orders.

For example, Canada Post (which handles most of our shipments) tell us that there are a large number of countries that will not accept mail from Canada. The information can be found here:

Canada Post – International Delivery Service Alerts

Destinations to which service is suspended (pdf)

As you can see, some countries such as New Zealand and India will accept certain types of mail, but not our small packet air mail shipments. We regret to say that any order made from a country that we are unable to ship to will cancelled, and the money will be refunded.

Thank you for your patience. We are not over this yet.

Elm Remains Closed

As the Covid-19 pandemic continues, we have decided to keep our offices closed. We will reopen once the government tells us that it is safe for us to do so.

The shopping cart on our web site has been disabled, as we do not want you to think that we will be able to ship product to you any time soon. You may still view and download data sheets, application notes, etc.

Thank you for your continued understanding.
