The ELM415 data sheet has been revised

We've taken some recent comments and used them to better the data sheet for the ELM415 Up/Down Interface IC. There's more information, and (hopefully) some clearer explanations.

As always, if you want to provide feedback to us on any of our products or their data sheets, please send an email to feedback@elmelectronics.com.

The ELM328 has been updated!

The ELM328 IC has now been updated to support all of the ELM327 v1.4 AT Commands. You still can not send any OBD commands with it, but we have changed the responses when you try (it now acts as if there is no ECU connected).

Note - This IC is only for developers that need to try the @2 and @3 commands multiple times with their software. It is not for use in scan tools.

The ELM327 v1.3a is still available!

We are still offering the ELM327 v1.3a IC, but have dropped the price.

It is now available for CAD19.00 each, for any quantity!

Many people find the v1.3a more than adequate for their needs, so we will carry it as long as there is demand for it. For more information, and the v1.3a data sheet, visit our OBD integrated circuits page.

The new ELM327 v1.4 is now available!

It's here, and available for purchase. The ELM327 has been improved once again, with more error checking, code improvements, and of course, new features. Here are a few of the new features:

• Power Control with a low power standby mode
• A 4800 baud ISO option
• A non-volatile memory location for storing user data
• CAN extended addressing support

The price of this new chip remains at CAD32.50 in single quantities, and the data sheet is still a free download. For more information, go to the OBD integrated circuits page.

Yes, you can now follow Elm Electronics on twitter. Twitter is a very convenient way for you to keep up with any changes that we make, without having to visit our site. We'll send tweets when we've done something that might interest you - introduced a new product, updated an old one, changed prices, etc. and you can decide if you want to look into it further. Don't worry, they won't be so frequent as to be a problem.

Want to light your Christmas tree?

Nov '09 - There's a new IC for sequencing LEDs. Typically these will be on a Christmas tree, but you might want to put them around a sign, in your window, or even in your car. Have a look at the chip, and download a copy of the data sheet:

ELM711 - Christmas LEDs Driver

New Web Site

Sept '09 - We've updated our web site. The main purpose was to reorganize the pages to make it easier to find the ones most often visited - products and help, but we also thought it was time for a new look.
If you have a suggestion or an idea for the site, please share it with us by sending an email to:

AN04 - ELM327 and Bluetooth Application Note

July '09 - Many of you have asked about using a wireless Bluetooth connection between the ELM327 and your computer, PDA, netbook, internet tablet, etc. This Application Note offers a few suggestions as to how you might do this, whether by adding an external adapter, or by permanently connecting a module in your ELM327 circuit.
Visit our Application Notes page to download this Note.

New Application Notes

If you are having trouble telling which wire is which on a transistor, then the new 'AN01 - Transistor Testing' Application Note is a must read. We've also added a few that are particular to the ELM327 and will be adding more.
Visit our Application Notes page to see all of the Application Notes.

There's a new debounce chip!

Feb '09 - For several years, people have been asking that we make more ICs like our ELM410 and ELM411 debounce circuits. Some wanted slightly longer debounce times, and others asked that we provide a pulse on input change. Well, we've done that with the new ELM409 Versatile Debounce Circuit. This new IC provides eight different modes of operation, adds a Schmitt trigger input, and has complementary outputs. It may not have three inputs, but it sure makes use of the one that it has.

We've updated the ELM304 data sheet

Jan '09 - We've updated the ELM304 NTSC Video Generator data sheet, expanding on some of the information, and including some 'scope traces to better show how the circuit works.

We've revised the ELM334

Dec '08 - We've incorporated your feedback and revised the ELM334 Garage Doorman. The data sheet has also been improved, adding several new ways in which you might use the IC.

The ELM334 was designed to remotely show the position of a garage door, but it can also be used with almost any electrical switch or contact. A simple two wire connection is all that is needed to a remotely montor the switch state using red and green LEDs, and with the addition of only a few transistors these same two wires can be used to control an output for operating an electric garage door opener, reset a circuit, or generate an alarm. If you do use it as a garage door monitor, you won't go wrong - it's particularly handy for late at night when you're not sure if you closed the door or not.

Have a suggestion for an update, or a new product?

We'd like to hear it. Just send an email to: feedback@elmelectronics.com
